Q1 of 36 Page 121

Write sample space ‘S’ and number of sample point n(S) for each of the following experiments. Also write events A, B, C in the set form and write n(A), n(B), n(C).

Two digit numbers are formed using digits 0, 1, 2, 3, 4, 5 without repetition of the digits.


Condition for event A : The number formed is even


Condition for event B : The number formed is divisible by 3.


Condition for event C : The number formed is greater than 50.

Sample Space, S= {10, 12, 13, 14, 15, 20, 21, 23, 24, 25, 30, 31, 32, 34, 35, 40, 41, 42, 43,45, 50, 51, 52, 53, 54}


Number of sample points, n(S) = 25


The number formed is even , A = {10, 12, 14, 20, 24, 30, 32, 34, 40, 42, 50, 52, 54}


n(A) = 13


The number formed is divisible by 3, B = {12, 15, 21, 24, 30, 42, 45, 51, 54}


n(B) = 9


The number formed is greater than 50,C = {51, 52, 53, 54} n(C) = 4
