Suppose 60 overnight hotel guests are surveyed to determine what they ate for breakfast with the following result:
27 had eggs, 22 had bacon, 36 had toast,
19 had eggs and bacon, 16 had eggs and toast, 15 had bacon and toast, 12 had eggs bacon and toast
A guest is selected at random. Find the probability that the guest had:
(a)none of the three
(b)toast but neither eggs nor bacon
(c)eggs and bacon but not toast
(d)bacon only

I think something is wrong with the problem.no key to the problem therefor choose A
at most 47 had breakfast.12 had eggs bacon and toast
4 eggs and toast 3 had bacon and toast 7 had eggs and bacon
total 23 eggs 22 bacon 19 toast 4eggs ang 17toast were rest A guest is selected at random only eggs and toast no bacon eliminate C,D and B therefor choose A
what is it ?
Too simple. Too naive.
