Given : Two friends x and y appeared for an audition.
The probability of selection of x is 2/5 and that of y is 1/7.
To Find: the probability that both of them are selected.
Solution:
probability of selection of x is 2/5
P(x) = 2/5
probability of selection of y is 1/7
P(y) = 1/7
Both events are independent
Hence probability that both of them are selected. = P(x).P(y)
= (2/5) (3/7)
= 6/35
the probability that both of them are selected. is 6/35
