QUESTION 3 Suppose a gambler plays roulette 900 times, betting $1 on each play on red. Recall from the previous week's that the gambler has a 18 chances in 38 to win. Thus the box model contains 18 +$1 tickets and 20 -$1 tickets. On average, playing one game, the gambler will lose $. Round your answer to the nearest cent. Must enter answer in the format 0.AB where A and B are integers. Playing 900 times, the gamber will lose, on average, $. Your answer should be an integer with no decimals. Using the short-cut formula, the standard deviation(SD) for the box model is . Round your answer to the nearest integer, for example, if the answer is 1.5, enter 2. The standard error(SE) for playing 900 times is $. Thus, in summary, the gambler can expect to lose $, give or take $ or so.
