Three digit numbers are formed using the digits 0, 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?
Total numbers of 3 digit that can be formed using 0,2,4,6,8 = 4× 5 × 5 = 100
3-digit number formed using 0,2,4,6,8 with all digits same are 222,444,666,888
∴ P(number has the same digits) = 4/100 = 1/25
As our answer matches only with option (d)
∴ Option (d) is the only correct choice.
