Use the fact that the mean of a geometric distribution is muequalsstartfraction 1 over p endfraction and the variance is sigma squared equals startfraction q over p squared endfraction . a daily number lottery chooses three balls numbered 0 to 9. the probability of winning the lottery is startfraction 1 over 1000 endfraction . let x be the number of times you play the lottery before winning the first time
find the mean, variance, and standard deviation.
