The sample space of a random experiment is {a, b, c, d, e, f}, and each outcome is equally likely. A random variable is defined as follows:
Outcome a b c d e f
X 0 0 1.4 1.4 2 3
Determine the probability mass function of X. Use the probability mass function to determine the following probabilities.
A) P(X = 1.6).B) P(0.5 < X < 2.7).C) P(X > 3).D) P(0 ≤ X < 2).E) P(X = 0 or X = 2).
Answer:
X ____ : 0 ______ 1.4 _____ 2 _____ 3
P(X) ___ 1/3 _____ 1/3 _____ 1/6 ____ 1/6 ;
0 ;
1/2 ;
0 ;
2/3 ;
1/2
Step-by-step explanation:
Each has the same probability ;
X ___ : 0 ___ 0 ___ 1.4 ____1.4 ___ 2 ___ 3
P(x) __ 1/6 __1/6 ___ 1/6 ___ 1/6 ___1/6 __ 1/6
Probability : required outcome / Total possible outcomes
X = 0
P(x = 0) = 1/6 + 1/6 = 2/6 = 1/3
X = 1.4
P(x = 1.4) = 1/6 + 1/6 = 2/6 = 1/3
X = 2
P(X) = 1/6
X = 3
P(x) = 1/6
Hence ;
X ____ : 0 ______ 1.4 _____ 2 _____ 3
P(X) ___ 1/3 _____ 1/3 _____ 1/6 ____ 1/6
A) P(X = 1.6).B) P(0.5 < X < 2.7).C) P(X > 3).D) P(0 ≤ X < 2).E) P(X = 0 or X = 2).
A.)
P(X = 1.6) = 0
B.)
P(0.5 < X < 2.7) = p(x = 1.4) + p(x = 2)
P(0.5 < X < 2.7) = 1/3 + 1/6 = (2 + 1) / 6 = 3/6 = 1/2
C.)
P(X > 3) = 0
D.)
P(0 ≤ X < 2) = P(0) + P(1.4)
P(0) + P(1.4) = 1/3 + 1/3 = 2/3
E.)
P(X = 0 or X = 2) = 1/3 + 1/6 = (2 + 1)/6 = 3/6 = 1/2
g Use the information below for questions 1 through 5. A San Francisco-based tech firm is able to keep 80% of its new employees after one year. Assume that the retention probability of each new employee is independent of other employees. Q1. What is the chance that two randomly sampled new employees will both be able to survive their first year
Answer:
0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year
Step-by-step explanation:
For each employee, there are only two possible outcomes. Either they survive the first year, or they do not. The probability of an employee surviving the first year is independent of other employees. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
A San Francisco-based tech firm is able to keep 80% of its new employees after one year.
This means that [tex]p = 0.8[/tex]
Q1. What is the chance that two randomly sampled new employees will both be able to survive their first year
This is P(X = 2) when n = 2. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{2,2}.(0.8)^{2}.(0.2)^{0} = 0.64[/tex]
0.64 = 64% probability that two randomly sampled new employees will both be able to survive their first year

Answer:
Dark Blue
Step-by-step explanation:
The easiest way it to assume X = 0. This will make the parentheses equal to 1 in each equation. So, the Y value will be the number in front of the parentheses.
The first will make the point (0,27)
the sum of two numbers is 5 and difference of their square is 5 find the difference if number
Answer:
x+y=5...i
x²-y²=5...ii
from i, x+y=5
x=5-y...iii
substitute iii in ii
(5-y)²-y²=5
25-2y²=5
2y²=20
y²=10
y=✓10
put y=✓10 in i
x+✓10=5
x=5-√10

the length of the Boston Marathon is about 26 miles. A mile is equal to 1.609 kilometers. How many kilometers does a runner cover if he or she completes in the race
Answer:
41.834
Step-by-step explanation:
The complete length of the boston marathon is 26 miles
A mile is 1.609 kilometers
Therefore the number of kilometers a runner needs to run to complete the race can be calculated as follows
= 26 × 1.609
= 41.834
Hence the runner needs to run 41.834 kilometers

Ayden earned a grade of 89% on his multiple choice history final that had a total of
200 problems. How many problems on the final exam did Ayden answer correctly?
Answer:
178
Step-by-step explanation:
Method 1: Set up a proportion
Set up an equation of the form:
\frac{\color{red}{\text{part}}}{\color{orange}{\text{whole}}}=
whole
part
=
\,\,\frac{\color{blue}{\text{percent}}}{100}
100
percent
Assign the variable xx to the unknown value:
\color{red}{x}=
x=
\,\,\color{red}{\text{part}}
part
The question asks what \textit{part}part of the total questions is 89%
Substitute the known values with the numbers given in the problem, and the unknown value with xx:
\frac{\color{red}{x}}{\color{orange}{200}}=
200
x
=
\,\,\frac{\color{blue}{89}}{100}
100
89
Solve for xx:
100\cdot\color{red}{x}=
100⋅x=
\,\,\color{orange}{200}\cdot\color{blue}{89}
200⋅89
Cross multiply
\frac{100x}{100}=
100
100x
=
\,\,\frac{17800}{100}
100
17800
Divide both sides by 100
178
Simplify
Method 2: Convert to decimal and multiply
{89}{100}=0.89
89%=
100
89
=0.89
Move decimal 2 places to the left
{Multiply result by the total:}
Multiply result by the total:
0.89{200}=
0.89⋅200=
