Suppose for a certain microRNA of size 20, the probability of getting a purine is binomially distributed with a probability of 0.7. There are 100 of these microRNAs, each independent of the other. Let Y denote the average number of purine in these microRNAs. Find the probability that Y is greater than 15.
Homework Answers
Y follows Binomial (100, 0.7)
P(Y=y) = 100Cy * 0.7y * 0.3100-y
P(Y>15) = Sum all values of y from 16 to 100 over P [Y=y)
P(Y>15) = 0.999999
