Document Summary

If looking at two events with numerical outcomes, we can look at a scatterplot of see what the correlation is between them: ex: chad is taking a statistics class and a history class. The probability that he passes statistics is 0. 9. The probability that her car has a mechanical issue is 0. 02. On the first try she has probability 0. 2 of passing. If she fails on the first try, her probability on the second try increases to. 0. 3 because she learned something from her first attempt. If she fails on two attempts, the probability of passing on a third attempt is 0. 4. She will stop as soon as she passes. The course rules force her to stop after three attempts in any case. Notice that she has different probabilities of passing on each successive try. Explain how to simulate one repetition of elaine"s tries at the exam. Simulate 10 repetitions and estimate the probability that elaine eventually passes the exam.
