Answer:

Probability of getting 3 consecutive tails in a fair coin toss:-

P(E)=0.125

Explanation:

If we toss an unbiased coin exactly three time we can have 8 outputs possible and those outputs are as following:-

HHH
HHT
HTH
HTT
THH
THT
TTH
TTT

Out of these 8 outputs we have 1 favorable outcome that is TTT.So the probability of the event is P(E)=1/8

where 8 is total number of outcomes.
