Question

When a scientist conducted a genetics experiments with​ peas, one sample of offspring consisted of 921 ​peas, with 698 of them having red flowers. If we​ assume, as the scientist​ did, that under these​ circumstances, there is a 3/4 probability that a pea will have a red​ flower, we would expect that 690.75 ​(or about 691​) of the peas would have red​ flowers, so the result of 698 peas with red flowers is more than expected.

A) If the​ scientist's assumed probability is​ correct, find the probability of getting 698 or more peas with red flowers. 

B) Is 698 peas with red flowers significantly​ high?
