Answer:
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%
