Question

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.Find the probability that both of them are selected.


​

Answer 1

Answer:

2/35

Step-by-step explanation:

probability of both events to take place=product of individual probabilities

p(both)=2/5*1/7=2/35

Answer 2

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
