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
