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:-

  1. HHH
  2. HHT
  3. HTH
  4. HTT
  5. THH
  6. THT
  7. TTH
  8. 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.
