Question

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?

Answer 1

Answer with explanation:

P=An Accurate order can contain orders from many of the restaurants, that is either from Restaurant A, Restaurant B,C,.D,........

P={A,B,C,D,E,F,G,......}

And taking an order from restaurant A, is another event.

Q={A}

→P ∩ Q={A}

 Which is not disjoint.

This can be explained with the help of Venn diagram also.
