Answer:
259 students
Step-by-step explanation:
First, find how many will check out science fiction books
350(0.14)
= 49
Find how many will check out sports books
350(0.12)
= 42
Subtract these amounts from 350
350 - 49 - 42
= 259
So, she should expect 259 students not to check out science fiction and sports books

Step-by-step explanation:
See how many times 30 fits into 383.
30 x 12 = 360, 30 x 13 = 390
therefore, 30 fits into 383 twelve times.
383 - 360 = 23
you'll have a remainder of 23

Answer:the probability that exactly five customers make a purchase is 0.033
Step-by-step explanation:
The formula for binomial distribution is expressed as
P(x = r) = nCr × q^(n - r) × p^r
Where
p = probability of success
q= probability of failure
n = number of sample
From the information given,
39 percent of all customers who enter a store will make a purchase. It means that the probability of success, p = 39/100 = 0.39
The probability of failure q, would be 1 - p = 1 - 0.39 = 0.61
n = 6
The probability that exactly five customers make a purchase is expressed as
P(x = 5) = 6C5 × 0.61^(6 - 5) × 0.39^5
P(x = 5) = 6 × 0.61× 0.39^5 = 0.033
