The probability that Pete exceeds 200 in at least 9 of his next 10 games is 0.268+0.1074 = 0.3754
<h3>What is Probability ?</h3>
Probability is defined as the likeliness of an event to happen.
It has a range of 0 to 1.
It is given that
Pete, a professional bowler, is unhappy with any game below 200
80% of his games exceed this score.
the probability that Pete exceeds 200 in at least 9 of his next 10 games is given by
P( 9/10 > 200) +P(10/10>200)
The binomial experiment consists of n trial out of it x is success.

Here p = 0.8
For 9/10 matches

For (10/10 >200)

Therefore the probability that Pete exceeds 200 in at least 9 of his next 10 games is 0.268+0.1074 = 0.3754.
