koban [17]

Let number of hits by Sanchez be x.

Number of hits by Washington = 18 + x

Total number of hits = 292

x + 18 + x = 292

2x + 18 = 292

2x = 274

x = 137

Hence, Sanchez has 137 hits and Washington has 155 hits.

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=9, p=0.51)$
