The following table gives the row and column totals of the given information.Let event A be the order from restaurant A and K be the order is accurate. The probability of getting an order from Restaurant A or an order that is accurate is calculated as follows: Disjoint events: Any two events said to be disjoint if they do not occur together or no common elements. In other words, the probability for the intersection of two disjoint events is zero. Here, Therefore, the events of selecting an order from Restaurant A and selecting an accurate order are not disjoint events.

Answered: Use the data in the following table,…

Question

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	D
Order Accurate	315	276	247	134
Order Not Accurate	40	60	30	14

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?
