2. A multiple choice test consist of 40 questions with possible answers of a , b , c, d, and e. Find the probability of getting at most 30% correct if all answers are random guesses.
In problems 1-4, do the following (A) Find the indicated binomial probability by using table A-1 in Appendix A. (B) IF np > or = to 5 and nq is > or = to 5, also find 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.
* tha A-1 chart is the binomial probability chart
1 With n = 14 and p = 0.6, find P (fever than 9)
SInce its less then 15, i can use this a-1 chart i have, but I"m not sure how to do it when it says FEWER or GREATER than 9
