Well question 7 is a Binomial distribution with n = 10 and p = 0.3

If we say that P is the distribution of public transport users, can you work out $\displaystyle \begin{align*} \textrm{Pr}\, \left( P = 4 \right) , \textrm{ Pr}\, \left( P \leq 2 \right) , \textrm{ Pr}\, \left( P \geq 3 \right) \end{align*}$?
