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.

Answer:
45 pages
Step-by-step explanation:
Caleb read a total of 30 pager over 2 hours.
To find the unit rates
2 hours of reading = 30 pages
1 hour of reading = x
Cross Multiply
2× x = 30 × 1
2x = 30
x = 30/1
x = 15 Pages.
Hence, he read 15 pages per hour
After a total of 3 hours of reading this week, how many pages will Caleb have read in all?
If;
1 hour = 15 pages
3 hours = x pages
Cross Multiply
x = 3 × 15 pages
x = 45 pages
Hence, Caleb would have read 45 pages in all
