#### Solution Preview

p= 0.7 or 70.00% (70% of Canadians submit their income tax returns by March 31)

q=1-p 0.3 or 30.00% (remaining 30% of Canadians do not submit their income tax returns by March 31)

This is a Binomial distribution

A) What is the probability that 9 or more will submit their return by March 31?

Probability that 9 or more will submit their return by March 31=
