Blood type B is relatively rare in the population, with a probability of .10. If we randomly selected three people and determined if their blood type was B (Yes or No), what is the number of combinations of outcomes for the sample space (hint, 1 outcome is YYY)? A. 8 B. 6 C. 3 D. 4
Homework Answers
Number of possible outcomes are
| first | second | third |
| Y | Y | Y |
| Y | Y | N |
| Y | N | Y |
| Y | N | N |
| N | Y | Y |
| N | Y | N |
| N | N | Y |
| N | N | N |
Therefore number of possible outcomes are

the type of protein?
2 What is the probability that at most four have the type of
protein?

A hospital has an urgent need for three units of type A+ blood. Assume that approximately 33% of the population has this type of blood. If there are 10 people waiting to donate one unit of blood, what is the probability that the hospital will be able to meet its need? (Hint Subtract the probability that fewer than three people have A+ blood from 1.) The probability that the hospital gets at least three units of blood is (Round to...

1.Suppose we have two bowls full of candies. Each bowl contains four different flavours of candy – grape (which are purple), lemon (which are yellow), cherry (which are red) and raspberry (which are also red). (a) [1 Mark] We will randomly select one candy from each bowl. The outcome of interest is the flavour of each of the two candies. Write out the complete sample space of outcomes. (b) [1 Mark] Suppose instead that we randomly select one candy from...
