Will give ! a survey asked students whether they have any siblings and pets.

Option B.

Step-by-step explanation:

The given table represents the relative frequency.

Let A and B represent the following events.

A : Student does not have a sibling

B :  Students has a pet.

Then intersection of A and B (A∩B) denotes the event that the student does not have a sibling but has a pet.

Using the given table it is clear that

P(A∩B) = 0.15

We need to find the probability that the student does not have a pet given that student has a sibling. It means we need to find the value of P(B|A).

Formula for conditional probability:

Substitute the given values.

The probability that the student does not have a pet given that student has a sibling is 60%.

Therefore, the correct option is B.

answer: kljdcdhjbdlchjad oac apoich a

step-by-step explanation:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
