Afair coin is tossed twice in succession. the set of equally likely outcomes is {hh, ht, th, tt}. what is the probability of getting exactly two tails?

0.25

Step-by-step explanation:

Given : A fair coin is tossed twice in succession.

The set of equally likely outcomes is {HH, HT, TH, TT}.

i.e. The total number of outcomes = 4

In order to get exactly two tails , the total number of favorable outcomes = 1  (TT)

We know that ,

Then, the probability of getting exactly two tails =

Hence, the required probability = 0.25
