Sketch a normal curve for each distribution. Label the $x$ -axis values at one, two, and three standard deviations from the mean.mean $=45,$ standard deviation $=2$
see graphThe graphs of two distributions are similar in sum of probabilities. It is equal to one inboth cases. In the first distribution, maximum probability occurs for 3 successes. Theprobability increases with increase in number of successes. In the second distribution,maximum probability occurs for 1 success. The probability increases gradually from 0 to1 success and then decreases.

when sketching a normal curve. You just wanted to your best to create a bell shaped graph for a hill, Harvey said. You know, right in the middle of that graph represents the mean or the average, which is 45. In its case, you always want to do three standard deviations away from the mean, so you want to go three above and three below the mean. You can call this one standard deviation, two standard deviations and three standard deviation. Negative one standards in the two standard deviations in negative three standard deviations. Now the actual numbers that go with these deviations, it's going to have something to do with two. When you go to the right, you just add 2 to 45 to get 47 49 51. When you go to the left, you subtract two from 45 to get 43 41 and 39. You were all done with this problem
