 ​Drive-thru Restaurant    A B C 337 278 231 123 36 52 40 15

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

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.

 ​Drive-thru Restaurant    A B C 316 270 241 148 37 60 30 15

If one order is​ selected, find the probability of getting an order from Restaurant A or an order that is accurate. Are the events of selecting an order from Restaurant A and selecting an accurate order disjoint​ events?

The probability of getting an order from Restaurant A or an order that is accurate is

To calculate the probability we will use addition theorem of probability.
