Question 1011626: Help please!
If np ≥5 and nq ≥5, estimate P(more than 6 right) with n=14 and p=0.3 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.
Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice.
A.
P(more than 6)=
​(Round to four decimal places as​ needed.)
B.
The normal distribution cannot be used.
