Drive-thru Restaurant Order Accurate Order Not Accurate 34 332 269 242 146 59 30 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 three decimal places as needed.) Are the events of selecting an order from Restaurant A and selecting an accurate order disjoint events? The events 'disjoint because itL--, possible to

Explanation / Answer

Solution:

total number of orders = 1123

Probability of getting an order from restaurent A or an order that is accurate = (332+34+269+242+146)/1123

= 0.9109

The events are not disjoint because it is possible to select an order that is both from restaurent A and an accurate order
