Question

For the following experiment write sample space ‘S’ and number of sample points n(S).

Two-digit numbers are formed using digits 2, 3 and 5 without repeating a digit.

Answer 1

 Let 'S' be the sample space

Sample Space (S) = {23, 25, 32, 35, 52, 53}

∴ n(S) = 6

Hence, the required number of sample spaces is 6.
