1, if right-handed 0, if left-handed. 10. Suppose the probability for a person to be right-handed is p. Let X = (a) What distribution does X follow? (b) A scientist selected a random sample of 1000 people. Let Y be the number of people who are right-handed, what distribution does Y follow? (c) This scientist found out that among the 1000 people, 100 are right-handed. He then estimated p to be 0.1. What theorem justifies his conclusion....

In a management trainee program, the probability a trainee is female is 0.63. The probability a female attended college is 0.45, while the probability a male attended college is 0.55. A management trainee is selected at random. (HINT - Draw yourself a tree diagram to answer the following questions!) Round each answer to 3 decimal places. Given that the management trainee did not attend college, what is the probability the person is a male ?

1 male white-tailed deer mates at random with each of 3 female deer. The male has bb at a locus that determines the size of antlers in male offspring (note - this is a simplified example B=Big, b=little). One female has BB, the second female has bB, and the third female has bb. Assuming that each allele (meaning letter corresponding to an antler type) has an equal probability of being passed on, what is the probability for each possible outcome?...
