Probability
Okay, I need help with this one.
Every time at bat, the probability that Isuke will get a hit is 25%. What is the probability that he will not get a hit in his next three consecutive times at bat?
Please explain it as well as answering it.

Read up on Binomial Probability.

(1-0.25)*(1-0.25)*(1-0.25)

The probability that he does not get a hit is .75 (1-.25=.75)

So the probability that he does not get a hit in his next 3 at bats is the Probability that he does not get a hit on the first times Probability that he does not get a hit on the second times Probability that he does not get a hit on the third

\$\displaystyle

=.75^3
