A bag contains 1 green, 4 red and 5 yellow balls. Two balls are selected at
random. Find the probability if there is no replacement of P(1 green and 1
yellow).

Answers

Answer:

The probability is 1/18.

Step-by-step explanation:

There are 10 balls in total. Let's start with the probability of just the green. There is 1 green ball.out of 10 balls total, so the probability of pickin just the green one would be 1/10. Since we aren't replacing the balls after we choose them, the total number of balls is now 9. now the probability of picking one yellow ball out of the nine balls left is 5/9 because there are 5 yellow balls. To get the probability of the green and yellow balls picked, we multiply the individual probabilities to get the actual probability of choosinf one green and one yellow ball without replacement. So multiply 1/10×5/9= 5/90, simplified to 1/18.

Two balls are selected at random, the probability of choosing two balls 1 green and 1 yellow without replacement is 1 / 20

Probability-based problem:

What information do we have?

Number of green balls = 1

Number of red balls = 4

Number of yellow balls = 5

Total number of balls = 1 + 4 + 5 = 10

Probability of green ball = 1 / 10

Probability of yellow ball = 5 / 10

Probability if there is no replacement of P(1 green and 1 yellow) = (1/10)(5/10)

Probability if there is no replacement of P(1 green and 1 yellow) = 1 / 20

HURRY PLEASE! AT LEAST ONE PARAGRAPH! Describe in words how to find the surface area of a cylinder if the radius is 5cm and
height is 18cm.

Answers

Answer:

722.57cm²

Step-by-step explanation:

Below, we have listed six basic equations that can be used to derive the explicit formulas of radius of a cylinder:

Volume of a cylinder: V = π * r² * h ,

Base surface area of a cylinder: A_b = 2 * π * r² ,

Lateral surface area of a cylinder: A_l = 2 * π * r * h ,

Total surface area of a cylinder: A = A_b + A_l ,

Surface Area of Cylinders. To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2.

The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h . ... Therefore, the volume of the cylinder is about 3016 cubic centimeters.

A barrel contained 60 gallons of water. Water leaked out of the barrel at a rate of 5 gallons every 3 days.


At this rate, how many days did it take for all 60 gallons of water to leak out of the barrel?
20 days
12 days
100 days
36 days

Answers

Answer:

36 Days!

Step-by-step explanation:

So A barrel contained 60 gallons of water. Water leaked out of the barrel at a rate of 5 gallons every 3 days. The question is “At this rate, how many days did it take for all 60 gallons of water to leak out of the barrel”? So What I did to find this out is multiplyed 3 by 12 to get 36 days. But When I was doing that I was also paying attention to that 5 gallons of water leak out of the barrel in 3 days, that’s why I multiplyed by 3.

If this doesn’t make sense to you I could explain it better if you need more explanation.
