Women who date John will decide to go on a second date with him with probability 0.3. (a) What is the probability that at least one of the next three women John dates will agree to go on a second date with him? Which distribution are you using, and what are the parameters? (b) What is the probability that John has to date four women until he finds one that agrees to go on a second date? Which distribution are you using, and what are the parameters? (c) If John spends on average $50 when he is on a second date what is the expected value and standard deviation of the amount of money he will spend on "second dates" after taking out three women on first dates?
