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 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 ... ? Round to 3 decimal places.

Restaurant A Restaurant B Restaurant C Restaurant D

Order Accurate 321 276 235 126

Order Not Accurate 32 56 40 11

The probability of getting an order from Restaurant A=0,321, (32,1%) and the probability of getting an order accurate in the Restaurant is 0,873 (87,3%)

Step-by-step explanation:

Number of orders: 321+276+235+126+32+56+40+11=1097

The probability of getting an order from Restaurant A.

The orders of restaurant A are the accurate + the not accurate = (321+32) = 353

A = (321+32) / 1097=0,321

Order Accurate: 321+276+235+126=958

Probability of getting an order accurate is orders accurate compare all the orders

958/1097=0,87329=87,329%

Probability of getting an order accurate in the Restaurant A is 321/353=0,90934=90,934%

Selecting an order from Restaurant A and selecting an accurate order are disjoint events
