I believe if I did this correctly, it should be 4 2/7, hope this helps!
Step-by-step explanation:
(a/b*b/c=1/2*3/4)(a/c=3/8)
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
Answer:
x=1
Step-by-step explanation:
14+2x+7=9x
2x-9x=7-14
-7x= -7
x= -7/-7
x=1
