對足球實在不了解...
請問faces a third-down situation with four yards needed for a first down是何意思...
還有一堆很難想像
請厲害的大大幫我翻出大概的中文就好
3.You\'re coach of a football team that faces a third-down situation with four yards needed for a first down. If you select a play involving a runoff tackle, the number of yards you will gain on the play is given by a normal random variable with mean 2.5 and standard deviation 1. What is the probability that you will make the first down if you run this play?
4.Consider the same situation as in Exercise 3. Another play you might run is a tricky end-around double reverse. The results of that play are given by a normal random variable with mean 3 and variance 6. What is the probability that you will make the first down if you run that play?

Yo! This has nothing to do with football.1. You have mu = 2.5 and sigma = 1. You are looking for P(x>4yards).2. You have mu = 3 and sigma = 6. You are looking for P(x>4yards).I think your professor is doing a poor job teaching you how to translate English into equations.If you really need the answers let me know. Otherwise, have a wonderful fkcing weekend.
