Answer #1

Solution :

It is supposed that we are in charge of the catering for a company meeting. The expected number of people for the meeting is 97 with a standard deviation of 5. If you order 100 sandwiches, we have to find the probability of having more people than sandwiches.

We have the following information fom the given data !

Thus , the probability of having more people than sandwiches is 0.2742531 ................... (Ans)
