Answers (1)

The probability that the number is divisible by 5 is \frac{1}{4}.

Hint:

Let 'S be set of all number formed by the digits 1,2,3,5 & 'A be the event of getting a number divisible by 5 .

So P(A)=\frac{n(A)}{n(S)}

Given:

Given digits a re 1,2,3 & 5

Explanation:

Assume S be set of all number formed by 1,2,3 and 5
A be the event of of getting a number divisible by 5.
n(s)= Number of numbers formed by 1,2,3 \& 5 =4!

n(A)=3!

So P(A)=\frac{n(A)}{n(S)}=\frac{3!}{4!}=\frac{1}{4}
This, the probability that the number is divisible by 5 is \frac{1}{4}.
