Question

Two coins are tossed at time find the probability of a head

Answer 1

total outcome = 4

favourable outcome = 2

probability = o.5

Answer 2

Experiment:Tossing two coins at a time

No. of possible outcome, n(s) =4

[(HH), (HT), (TH), (TT)]

E: Getting one head

No. of favourable outcome, n(E) =3

P (E)=3/4
