Answer:

x = 37.85
Step-by-step explanation:
Both of these conditions must be true in order for the assumption that the binomial distribution is approximately normal. In other words, if
and
then we can use a normal distribution to get a good estimate of the binomial distribution. If either np or nq is smaller than 5, then a normal distribution wouldn't be a good model to use.
side note: q = 1-p is the complement of probability p
Set the equations equal to each other
Subtract x from both sides
Divide both sides by -4
x=-1/2
This is impossible and it is not even an equation since
