Last week, a flower delivery business conducted a survey on customer happiness. They found that 56% of their customers were "pleased" with the service.If the company surveys 4 of their customers the next week, what is the probability that exactly 1 is pleased?Write your answer as a decimal rounded to the nearest thousandth.____
Q. Last week, a flower delivery business conducted a survey on customer happiness. They found that 56% of their customers were "pleased" with the service.If the company surveys 4 of their customers the next week, what is the probability that exactly 1 is pleased?Write your answer as a decimal rounded to the nearest thousandth.____
Use Binomial Probability Formula: Use the binomial probability formula: P(X=k)=C(n,k)⋅(p)k⋅(1−p)(n−k). Here, n=4, k=1, and p=0.56.
Calculate C(4,1): Calculate C(4,1) using the formula k!(n−k)!n!. So, C(4,1)=1!×(4−1)!4!=14=4.
Compute (0.56)1: Compute (0.56)1 which is just 0.56.
Calculate (1−0.56)(4−1): Calculate (1−0.56)(4−1) which is (0.44)3. So, (0.44)3=0.44×0.44×0.44=0.085184.
Multiply Values Together: Multiply all the values together: P(X=1)=4×0.56×0.085184. So, P(X=1)=4×0.56×0.085184=0.1905664.
Round to Nearest Thousandth: Round the answer to the nearest thousandth: 0.1905664 rounds to 0.191.
