The probability that person A will pass is 7/8 and the probability that person B will pass is 4/7 . Assume the events are independent. Find the probability that person A will fail given that person B will pass.

Therefore the probability that person A will fail given that person B will pass .

Step-by-step explanation:

Probability:

The ratio of the number of favorable outcomes to the number of all possible outcomes.

Given that,

The probability that A will pass the examination is and the probability that person B will pass the examination is .

The probability that A will fall is

Therefore the probability that person A will fail given that person B will pass

=P(A will fail)×P(B will pass)

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
