For #10-12, find the probability.

Write your answer as a decimal rounded to the hundredths place. The sample space for flipping a coin three times is listed below.

(HHH, HHT, HTH, HTT, THH, THT, TTH, TTT)

10. Round your answer to three decimal places. What is the probability that you flip a coin three times and the coin lands on Heads all 3 times?

11. Round your answer to three decimal places, What is the probability that you flip a coin three times not flipping heads at all?

12. Round your answer to three decimal places. What is the probability that you flip a coin three times and the coin lands on heads two times?

Answer :

Answer:

10. 0.125

11.  0.125

12. 0.375.

Step-by-step explanation:

The number of possible outcomes in the sample space = 8.

10. Prob (HHH) = 1/8 = 0.125.  ( as it only occurs once is the sample space).

11.  The possible outcomes are just TTT so the probability = 1/8 = 0.125.

12. Prob ( HHT or HTH or THH) = 3/8 = 0.375 (as there are 3 ways to get 2 heads.
