The layout of the data is as follows:

A B C D

Order Accurate- 315 277 234 120

Order not - 34 50 35 18

accurate

Like I said previously this is an or problem and this means it is an addition rule problem. The problem wants me to compute

the probability that whenever a single order is selected what is the probability that this probability is from restaurant A or C or an order that is not accurate.

I know the answer is .633 I just can't figure out how to set up the problem.
