Question

For a week, a clothing company tracks the amounts spent by its customers, with the results shown to the right.
a) What is the probability that a randomly chosen customer spent $120 or more?
b) What is the probability that a randomly chosen customer did not spend less than $80?
c) What is the probability that a randomly chosen customer spent between $40 and $159.99?
a) What formula should be used to find the probability that a randomly chosen customer spent $120 or more?
A. P($120 or more) = P($120-$159.99)
B. P($120 or more) = 1 - P($120 - $159.99)
O C. P($120 or more) = P($120-$159.99) + P($160-$199.99) + P($200 or more)
O D. P($120 or more) = P($120-$159.99) + P($160 - $199.99) - P($200 or more)
The probability that a randomly chosen customer spent $120 or more is
(Simplify your answer.)
b) What formula should be used to find the probability that a randomly chosen customer did not spend less than $80?
A. P(not less than $80)=P($0-$39.99)+ P($40-$79.99) + P($80 - $119.99)
B. P(not less than $80)=P($80 - $119.99)
