I got a C++ problem.
Let n be a positive integer and let S(n) denote the number of divisors of n. For example, S(1)- 1, S(4)-3, S(6)-4 A positive integer p is called antiprime if S(n)くS(p) for all positive n 〈P. In other words, an antiprime is a number that has a larger number of divisors than any number smaller than itself. Given a positive integer b, your program should output the largest antiprime that is less than or equal...

Q18 12 Points For any positive integer n, let bn denote the number of n-digit positive integers whose digits are all 1 or 2, and have no two consecutive digits of 1. For example, for n - 3, 121 is one such integer, but 211 is not, since it has two consecutive 1 's at the end. Find a recursive formula for the sequence {bn}. You have to fully prove your answer.

2) In the U.S., about 8.5% of people are B+ for blood type. You take a sample of size 9. You’re interested in people who are B+. Figure out the following probabilities: a) Pr{Y = 3} b) Pr{Y = 1} c) Pr{Y < 1} d) Pr{Y > 0} (hint - use (c) to answer this and make sure you know why this works)

Let X denote the number of times you have to play a game in order to win once. Assume attempts are independent, and that the chance of winning each time you play is p. (a) Find the probability that X is even (as a function of p). [Hint: You’ll use a geometric series from calculus.] (b) What happens to your answer to (a) as p → 1?
