Question

Brian flips a fair coin 3 times . What is the probability of getting 3 tails?

Answer 1

1/9 is the probability

Answer 2

1/8

Explanation:

Firstly, we need to rule out all the possible outcomes

[HHH], [HHT], [HTT], [TTT], [TTH], [THH], [HTH], [THT]

Since there are 8 possible outcomes and only one of the possible outcomes give us 3 tails, 1 is upon 8 ( 1 / 8 )
