Question

Orders for a computer are summarized by the optional features that are requested. The proportion of orders with no optional features is 0.29. The proportion of orders with one optional feature is 0.34. The proportion of orders with more than one optional feature is 0.37. (a) What is the probability that an order requests at least one optional feature? Round your answer to two decimal places (e.g. 98.76). (b) What is the probability that an order does not request more than one optional feature? Round your answers to two decimal places (e.g. 98.76).

Answer 1

(a) 71.00%

(b) 63.00%

Explanation:

No optional features = 0.29

One feature = 0.34

Two features = 0.37

(a) The probability that an order requests at least one optional feature is 100% minus the probability of an order requesting no optional features:

`P=1-0.29=0.71=71.00\%`

(b) The probability that an order does not request more than one optional feature is 100% minus the probability of an order requesting two optional features:

`P = 1 -0.37=0.63 = 63.00\%`
