One piece at a time:
4(p+2) means 4 times everything inside the parentheses.
That's
4(p) + 4(2) = 4p + 8 .
3(2p-3) means 3 times everything inside the parentheses.
That's
3(2p) + 3(-3) = 6p - 9 .
Now add everything up:
4p + 8 + 6p - 9 .
Add all the p's together: 4p + 6p = 10p
Add all the plain numbers together: 8 - 9 = -1
The final result is: 10p - 1 .

Answer:
B.0.15
Step-by-step explanation:
To approximate a binomial distribution as a normal distribution, two conditions must be met:
np > 10
nq = n (1−p) > 10
Here, n = 250. Check each value of p to see if it meets the conditions.
A. p = 0.03
np = 7.5, nq = 242.5
B. p = 0.15
np = 37.5, nq = 212.5
C. p = 0.02
np = 5, nq = 245
D. p = 0.97
np = 242.5, nq = 7.5
E. p = 0.99
np = 247.5, nq = 2.5
Of the five choices, only B meets both conditions.
