Two coins are tossed simultaneously. What is the probability of getting at most one head?

Total numbers of elementary events are: 2 x 2 = 4


Let E be the event of getting at most one head


Note: atmost one head means one head or no head at all, outcomes are considerable


Favourable events are: TT, HT, TH


Numbers of favourable outcomes = 3


P (E) = 3/4
