Error in calculation
Posted on 2016-07-19
Can you please help me in the calculation? Thanks.
A successful barbeque chain sells its beef, pork, and chicken items to three kinds of customers: dine-in, delivery, and pickup. Last year's sales showed that 12,766 orders were dine-in (d), 5,896 were delivery orders (e), and 3,124 orders were pickup (p). Suppose an audit of last year's sales is being conducted.
a. If a customer order is selected at random, what is the probability it will be a pickup order?
Pickup = 3124 / 12766+5896+3124
b. If two customer orders are selected at random, list the sample space indicating the type of order for both
(d, e), (d, p), (e, d), (e, p), (p, d), (p, e)
