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).

One coin and one die are thrown simultaneously.


Condition for event A : To get head and an odd number.


Condition for event B : To get a head or tail and an even number.


Condition for event C : Number on the upper face is greater than 7 and tail on the coin.

Sample Space, S = {H1, H2, H3, H4, H5, H6 T1, T2, T3, T4, T5, T6}


Number of sample points, n(S) = 12


To get head and an odd number , A = {H1, H3, H5}


n(A) = 3


To get a head or tail and an even number , B = {H2, H4, H6, T2, T4, T6}


n(B) = 6


Number on the upper face is greater than 7 and tail on the coin= No Sample space exists for this event as dice does not have numbers greater than or equal to 7


n(C)=0
