Three digit numbers are formed using the digits `Q, 2, 4, 6, 8. A` number is chosen at random out of these numbers what is the probability that this number has the same digits?

Options

A. `1//16`
B. `1//25`
C. `16//25`
D. `1//645`

Answer

B

Explanation

Given digits are 0, 2, 4, 6, 8.
Total number of cases `= 4 xx 4 xx 4`
(`because` We have 4 choices for each number)
`therefore` Required probability `= 4/64 = 1/16`
