Question

Each Saturday morning, Beau practices throwing pitches to his dad. His dad estimates the probability of each pitch Beau throws being a "strike" is 0.3. If each pitch is considered to be independent, what is the probability that the next three pitches thrown by Beau will all be strikes?

Answer 1

Answer: 0.27

Explanation:

Given that :

Probability of being a strike ; p(strike) = 0.3

Note : the probability of each pitch Beau is independent :

Probability that next three will be a strike :

p(strike) * p(strike) * p(strike)

= 0.3 * 0.3 * 0.3

= 0.27
