Classroom Examples:
- A jar on your desk contains twelve black, eight red, ten yellow, and five green jellybeans. You pick a jellybean without looking.
- What is the probability that the jellybean is green?
- What is the probability that the jellybean is not yellow?
- What are the odds in favor of picking a black jellybean?
- A family has three children. Using b to stand for boy and g to stand for girl, and using ordered triples such as (b, b, g) give:
- the sample space
- the event E that the family has exactly two daughters
- the event F that the family has at least two daughters
- the event G that the family has three daughters
- Mendel found that snapdragons have no color dominance; a snapdragon with one red gene and one white gene will have pink flowers. If a pure-red snapdragon is crossed with a pure-white snapdragon, find the probability of the following.
- a red offspring
- a white offspring
- a pink offspring
- If carrier-detection tests show that two prospective parents have sickle cell train (and are therefore carriers), find the probability of each of the following
- Their child would have sickle cell anemia.
- Their child would have sickle cell trait.
- Their child would be healthy (i.e., free of symptoms).
-
Tay-Sachs disease is a recessive disease.
If carrier-detection tests show that one prospective parent is a carrier of Tay-Sachs and the other has no Tay-Sachs gene, find the probability of each of the following. - The child would have the disease.
- The child would be a carrier.
- The child would be healthy (i.e., free of symptoms).
