hey there,

i just cant get my head around solving these questions... my textbook has not been of much help.

if you know the formulas i should be using, please let me know.

What you need to know:

12% of peoples first preference goes to cheese on crackers.

Question:

What is the probability that from a random sample of ten people, exactly four gave their first preference to having cheese?

im assuming its something like .12*4 and something about .88 but im not sure what order to use and what formula.

P(4 people want cheese)

-----------------------------------------------------------------------

and if you can do that, are you able to try this one also.

Question: what is the probability that from a random sample of 10 people, a MAJORITY gave their first preference to cheese?

Much appreciated if you can give me a heads up in the right direction
