The probability of randomly selected student who plays sport given that student is senior is 0.04
P(A) denotes probability of occurring of an event A
P(B) denotes probability of occurring of an event B
P(B/A) is known as condition probability.
The dependent events are the only ones that give rise to the conditional probability P(B/A). The conditional probability of B given that A has happened is provided.
According to this question A denotes as student is senior
B denotes student plays sport.
What is the probability that a randomly selected student plays a sport
given that the student is senior is same as conditional probability.
P(B/A) ->Condition probability of B given that A has happened.
Student is senior given we have to tell about student plays a sport.
P(B/A) = P(A∩B) / P(A)
Given that P(A∩B) = 0.10
P(A) = 0.25
P(B/A) = 0.10/0.25 = 0.4
