Question

use the data in the following table, which lists drive - thru order accuracy at popular fast food chains. assume that orders are randomly selected from those included in the table. if one order is selected, find the probability of getting an order that is not accurate. the probability of getting an order that is not accurate is □. (round to three decimal places as needed.)

Explanation:

Step1: Calculate total number of not - accurate orders

$33 + 60+40 + 15=148$

Step2: Calculate total number of all orders

$(326 + 277+250 + 140)+(33 + 60+40 + 15)=1141$

Step3: Calculate the probability

The probability $P$ of getting a not - accurate order is the number of not - accurate orders divided by the total number of orders. So $P=\frac{148}{1141}\approx0.1297$

Answer:

$0.130$
