Use the normal distribution to approximate the binomial distribution. A basketball player has a 75% chance of making a free throw. They will take 120 attempts. What is the probability of them making: a. more than 100 free throws? b. Fewer than 85 free throws?

* can you show me how to used the compliment (1- x) as short cut to get an answer instead of using standard normal cumulatative probablity table*
