PPT-Probability Distributions

A Brief Introduction Normal Gaussian Distribution Bellshaped distribution with tendency for individuals to clump around the group medianmean Used to model many biological phenomena Many estimators . 2/29/2012. Review. When playing roulette at the Bellagio casino in Las Vegas, a gambler is trying to decide whether to bet $5 on the number 13 or to bet $5 that the outcome is any one of these five possibilities: 0 or 00 or 1 or 2 or 3. From Example 8, we know that the expected value of the $5 bet for a single number is -26₵. For the $5 bet that the outcome is 0 or 00 or 1 or 2 or 3, there is a probability of 5/38 of making a net profit of $30 and a 33/38 probability of losing $5.. Understanding the meaning of the terminology we use.. Quick calculations that indicate understanding of the basis of methods..
