10. (6 pts) Slips of paper marked with numbers 1, 2, 3, 4, and 5 are placed in a box. After being mixed, two slips are drawn simultaneously. a) Find the probability that both slips are marked with even numbers. b) Find the probability that one slip is marked with an odd number and the other is marked with an even number. c) Find the probability that the sum is 10.
9. The four conditions required for using a Binomial distribution are. (a) A fixed number of trials (n). b) On each trial, there are two possible outcomes, one of which we call a "success" (c) On each trial, P(success) is the same (d) The outcomes of each trial are independent For each of the following decide if the random variable defined (X) is a Binomial variable or not. If it is not a Binomial variable, say which of the four...
