Question: With n = 15 and p = 0.4, find P (fewer than 3). Do the following: (a) Find the indicated binomial probability by using Table

With n = 15 and p = 0.4, find P (fewer than 3).

Do the following: (a) Find the indicated binomial probability by using Table A-1 in Appendix A. (b) If np ≥ 5 and nq ≥ 5, also estimate the indicated probability by using the normal distribution as an approximation to the binomial distribution; if np < 5 or nq < 5, then state that the normal approximation is not suitable.
