Question

Esme plans to flip a fair coin 3 times and record the results of each flip.

What is the probability that the coin lands with the heads side up on all 3 flips?
(put in fraction form)

Answer 1

Answer:

⅛

Step-by-step explanation:

P(H&H&H) = ½ × ½ × ½ = ⅛

Answer 2

Answer: 1/8

Step-by-step explanation:

When a coin is thrown 3 times , the sample space is

{HHH , HHT , HTH, HTT , THH ,THT ,TTH , TTT }

the coin lands with the heads side on all 3 flips only once out of the total sample space. That is

P( HHH) = number of times of HHH / sample space

P(HHH) = 1/8
