Diagrams of the normal distribution are almost mandatory

3. 40% of the population has type A blood.

If 8 people are selected at random, what is the probability that less than six of them have type A blood.

If 80 donors come to give blood one day, what is the probability that less than 60 of them have Type A blood (using the normal approximation)? Explain why this is higher or lower than the answer in part (a).

If 10 people give blood one day, what is the probability that more than 6 of them are Type A?

If 100 people come to give blood, what is the probability that more than 60 the donors is of Type A? Explain why this answer is higher or lower than the answer in part (c).
