20 % of biscuits made by a baker are chocolate chip cookies. 11 biscuits are selected at random. a) Assuming a binomial distribution for X , the number of chocolate chip cookies, write down the values of nand p X∼bin(n,p) n=? p=? b) Find the probability that our selection contains exactly 3 chocolate chip cookies. P(X=3)= (to 3 decimal places). Find the probability that our selection contains no more than 1 chocolate chip cookies. Probability = ? (to 3 decimal places).
