I. do these situations involve bernoulli trials? explain.

a. we roll 50 dice to find the distribution of the number of spots on the faces.

b. how likely is it that in a group of 120 the majority may have type a blood, given that type a is found in 43% of the population?

c. we deal 7 cards from a deck and get all hearts. how likely is that?

d. we wish to predict the outcome of a vote on the school budget, and poll 500 of the 3000 likely voters to see how many favor the proposed budget.

e. a company realizes that about 10% of its packages are not being sealed properly. in a case of 24, is it likely that more than 3 are unsealed?

B. We can use Bernoulli trials to find how likely is that the majority of a group of 120 people have type A blood, given that 43% of people have type A blood. There are two possible outcomes (a person eithr has Tpe A blood or does not), there is a constant probability of success (43% of people have Type A blood), and the trials are independent (wether each person has Type A blood does not depend wether others have Type A blood).
