Lesson 1: Binomial probability

# Graphing basketball binomial distribution

Sal graphs the results of using the binomial distribution to find the probabilities of making different numbers of free throws.

• In the 'Binomial distribution' video, the probability was calculated by finding the total number of events and then using the combinatorics formula to find the chance of X occurring however many times and dividing that by the total number of possibilities to get the probability. On the other hand in the 'Probability of making 2 shots in 6 attempts' the value derived from using combinatorics is multiplied with the probabilities to get the final answer. Why is there a difference in the two approaches ? Sorry my question is a little confusing
• He just skipped the multiplication part since both outcomes are equaly likely. If you multiply by the probabilities raised to the correct exponant, like he does here, it comes to the same result.
• at , you said "size". Did you mean to?
• At , Sal said "6 free throws". The caption is incorrect it says "size".
