Unformatted text preview: 1 Lecture 4.2 (cont.) Geometric Random Variables Geometric Probability Distributions Through 2/24/2011 NC States freethrow percentage was 69.6 (146 th of 345 in Div. 1). In the 2/26/2011 game with GaTech what was the probability that the first missed free throw by the Pack occurs on the 5 th attempt? 2 Binomial Experiments n identical trials n specified in advance 2 outcomes on each trial usually referred to as success and failure p success probability; q=1p failure probability; remain constant from trial to trial trials are independent The binomial rv counts the number of successes in the n trials 3 The Geometric Model A geometric random variable counts the number of trials until the first success is observed. A geometric random variable is completely specified by one parameter, p , the probability of success, and is denoted Geom( p )....
