Part 1,Using the Empirical Rule, in a normal distribution what percentage of values would fall into an interval of 76 to 304 where the mean is 190 and standard deviation is 57? Please format to 3 decimal places.

Part 2,What is the Binomial Probability when the number of trials is 15, probability is 0.71, and we want less than 6 successes. Use 4 decimal places.

Part3What is the Variance for the following discrete probability distribution?

x	P(X)
0	0.04
1	0.17
2	0.64
3	0.1
4	0.05
