Normal distribution finding probability between 2 numbers
2020年8月23日 · what is the probability that between 33 and 36 are female? This looks like a normal distribution question to me. Therefore, if there can be as many males as females. The probability of female answering the call is 0.50%. The average number of female would be 35 (70 * 0.5) Let's say the standard deviation is 1 since the call count from 1,2,3,4,5 ...
Finding probability using moment-generating functions

statistics - How can I find a probability given just mean and …
$\begingroup$ In principle, we need quite a bit more than mean and variance. If we use the normal approximation, the estimated probability is small, and the true answer is small, so the difference between estimate and truth will be small.
Probability for 3 of a kind - Mathematics Stack Exchange
2016年3月1日 · You have the probability that the first three cards you draw will be the same and the next two both different. $~$ However, the order of drawing the cards should not matter. $~$ Hence you should multiply your result by $\frac{5!}{3!2!}$, the count of ways to select places for the three of a kind.
