Q2 of 23 Page 1

Attempt any four of the following subquestions:

Two coins are tossed simultaneously. Write the sample space (S), n(S), the following event A using set notation and n(A), where ‘A is the event of getting at least one head.’

Sample Space denotes all the possible outcomes of the two tosses.

S = {HH, HT, TH, TT}


Here, n(S) = 4


Now, let A is the event of getting at least one head.


A = {HH, HT ,TH}


⇒ n(A) = 3
