Question

For each of the following experiments write sample space ‘S’ and number of sample Point n(S) 

i. One coin and one die are thrown simultaneously. 

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

Answer 1

i. Sample space,

S = {(H, 1), (H, 2), (H, 3), (H, 4), (H, 5), (H, 6), (T, 1), (T, 2), (T, 3), (T, 4), (T, 5), (T, 6)}

∴ n(S) = 12

ii. Sample space,

S = {23, 25, 32, 35, 52, 53} 

∴ n(S) = 6
