Find a table of the Binomial random variable (include a picture
of the table in your submission) and obtain the probability that in
20 independent trials, each of which has probability of success
equal to 0.1, the number of successes is less than or equal to
3.
Repeat the problem using instead of a Binomial a Poisson with
suitable parameter lambda.
