Question

Two coin are tossed together. Find probability of getting
1) at least one tail
2)one head and one tail​

Answer 1

Total number of outcomes = 4

1) The number of favorable outcomes = 3 P(atleast one tail) = No.of favorable outcome/

Total number of outcomes

=3/4

2) The number of favorable outcomes = 2

P(1 head and 1 tail)=No.of favorable outcome/

Total number of outcomes

=2/4

=1/2

Answer 2

Answer:

1) 3/4

2) 1/2

Total outcomes are HH, TT, HT, TH

P( at least one head) =3/4

P(one head and one tail) =2/4=1/2
