Question

when two coins are tossed what is the probability of not getting exactly two tails​

Answer 1

Answer:

3/4 is the probability of not getting exactly two tails.

Answer 2

Let E1   = event of getting no tail. Then,E  

={HH} and, therefore, n(E1 )=1

Therefore, P(getting no tail) =P(E  

n(S) /

n(E1)      =1/4
