The probability is 1/4
This is because:
Probability of first tails = 1/2
Probability of second tails = 1/2
Probability of first AND second tails = 1/2 * 1/2
= 1/4
This is also visible in the set of outcomes

Answer: 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 , [tex]\text{Probability }=\dfrac{\text{Favorable outcomes}}{\text{Total number of outcomes}}[/tex]

Then, the probability of getting exactly two tails = [tex]\dfrac{1}{4}=0.25[/tex]

Hence, the required probability = 0.25
