Question

Two coins are tossed at the same time find the probability that one head is obtained

Answer 1

P(E)=3/4 since 4 oucomes HH,TH,HT,TT and only 3 have atleast 1 H

Answer 2

outcomes: HH, TT, HT, TH
favourable outcomes = 2
and total outcomes = 4
let the probability of the event be P(E), then
P(E) = favourable outcomes/total outcomes
= 2/4 = 1/2 = 0.5 Ans.
