Question

In a single throw of two coins, find the probablity of getting 1. both tails 2. at least 1 tail 3. at the most 1 tail

Answer 1

P={hh,ht,the,TT}
1)Q={tt} probability of q= 1/4
2) S={ht,th,TT} probability of s= 3/4
3)R={th,ht} probability of r = 1/2

Answer 2

1. P(both tails) =
favorable outcomes/total outcomes
1/4
2. P(at least one tail) = 3/4
3. P(at most one tail) = 2/4 = 1/2
