squares.

(a) Using the Binomial, Poisson and Normal distributions, write down formulas for

the probability that a single chocolate bar has at least 3 but no more than 7 deadly

squares. ...

Note: Use the expectation of the Binomial distribution for the Poisson distribution.

Use the expectation and the standard deviation of the Binomial distribution for

the Normal distribution. In the formulas based on the Binomial and Poisson

distributions use the Psymbol as shown in the lecture notes. The formula based

on the normal distribution should be an integral.

(b) Use either your calculator or the Scientific Notebook functions BinomialDist, PoissonDist
