Answer:
(a) 71.00%
(b) 63.00%
Step-by-step 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:
[tex]P=1-0.29=0.71=71.00\%[/tex]
(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:
[tex]P = 1 -0.37=0.63 = 63.00\%[/tex]
