Complete question is;
A lot of 10 components contains 4 that are defective. Two components are drawn at random and tested. Let A be the event that the first component drawn is defective, and let B be the event that the second component drawn is defective. Write your answer as a fraction or a decimal, rounded to four decimal places.
(a) Find P(A)
(b) Find P (B|A)
(c) Find P(A and B)
(d) Are A and B independent?
Answer:
A) P(A) = 0.4
B) P(B|A) = 1/3
C) P(A and B) = 2/15
D) They are not independent
Step-by-step explanation:
We are told that A is the event that the first component drawn is defective, and B is the event that the second component drawn is defective.
A) Since 4 out of the 10 components are defective, then;
P(A) = 4/10 = 0.4
B) After taking 1 out of the 10, there will be 9 left and 3 defective ones left.
Thus; P(B|A) = 3/9 = 1/3
C) P(A and B) = P(A) × P(B|A)
Thus;
P(A and B) = 4/10 × 1/3
P(A and B) = 4/30 = 2/15
D) They are not independent because B can't be done until A is done whereby the first component is drawn.

Which is a better deal 12.4 ounces for $4.99 or 21 ounces for $6.49?
Answer:
Getting 21 ounces for $6.49 is a better deal!
Step-by-step explanation:
4.99 / 12.4 = 0.402419...
6.49 / 21 = 0.30904...
0.4 is larger than 0.30 therefore 0.30 is less and a better deal.
Have an amazing day! ^-^

Step-by-step explanation:
Meg pounded a stake into the ground. When she attached a leash to both the stake and her dog’s collar, the dog could reach 9 feet from the stake in any direction. Using 3.14 for pi, what is the approximate area of the lawn, in square feet, the dog could reach from the stake.
The dog is able to run around in a circle with a radius of9 ft.
The area of a circle is A = pi r^2
A = (3.14) (9)^2
A= (3.14)(81)
A= 254.34 sq ft

Evaluate the function, find f(-2):
f(x) = 2x^2 +3x
Answer:
B) 2
Step-by-step explanation:
f(-2) = 2 * (-2)^2 + 3(-2)
f(-2) = 2 * 4 - 6
f(-2) = 8 - 6
f(-2) = 2

PLZ HELP ASAP WILL MARK U BRANLYEST... thanks:)
Step-by-step explanation:
Here we are going to use the Pythagoras theorem to get the Hight of the Television
[tex] {42}^{2} - {32}^{2} = x[/tex]
X Being the unknown side
[tex] {42}^{2} - {32}^{2} = 740 \\ x = \sqrt{740} = 27.2[/tex]
So the height is 27.2in
The Are of the screen would be L x B
27.2 x 32 = 870.2 in^2
We will use Pythagoras for the last question also
[tex] {40}^{2} + {32}^{2} = 2624 \\ \sqrt{2624} = 51.23[/tex]
She will need 51.23 in screen size
