Two brother X and Y appeared for an exam. The probability of selection of X is 1/3 and that of B is 2/5. Find the probability that both of them are selected.
Answer/Solution
2/15
Steps/Work
Explanation:
Let A be the event that X is selected and B is the event that Y is selected.
P(A) = 1/3, P(B) = 2/5.
Let C be the event that both are selected.
P(C) = P(A) × P(B) as A and B are independent events:
= (1/3) × (2/5) = 2/15
Answer: B) 2/15
Let A be the event that X is selected and B is the event that Y is selected.
P(A) = 1/3, P(B) = 2/5.
Let C be the event that both are selected.
P(C) = P(A) × P(B) as A and B are independent events:
= (1/3) × (2/5) = 2/15
Answer: B) 2/15
