39 percent of all customers who enter a store will make a purchase. suppose that 6 customers enter the store and that these customers make independent purchase decisions. (1) use the binomial formula to calculate the probability that exactly five customers make a purchase.

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

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
