You can use a binomial probability table, or calculate by hand using the following formula: P(x) = (nCx)(p^x)[q^(n-x)]

For the second part:

Use the binomial approximation to a normal distribution.

mean = np = 50 * .10 = ?

standard deviation = √npq = (√(50 * .10 * .90) = ?

Note: q = 1 - p

Finish the calculation.

I hope these few hints will help.
