I am a student at KNUST. I am a great learner and a good tutor as well. Math is my stronghold although I very much like Chemistry and Mechanics. I decided to sign up as a tutor so I can help solve problems, provide insights and make lessons quite interesting.

Alon plays on the SUNY Fredonia Men's Basketball team. Assume he makes 75% of his free throws. Also, assume independence from one free throw attempt to the next. One day after practice, Alon attempts 20 free throws. Let X be the number he makes.(a) Specify the distribution of X. (That is, indicate the type of distribution it has and what the parameters are.)(b) Compute the probability that X = 12.(c) Compute the probability that X is at most 17.(d) Compute the expected value (mean) of X.
