The probability of a failure is 0.5

  • Probability is the likelihood or chance that an event will occur.

  • Probability  = Expected outcome/Total outcome

  • Since Janie flips a coin 70 times, then the total outcome is 70

The probability of getting a failure will be 50% of the total times;

Expected outcome  = 50% of 70

Expected outcome = 35

Pr(a failure) = 35/70

Pr(a failure) = 0.5

Hence the probability of a failure is 0.5
