Suppose we are given a probability distribution that has a mean if 14

Suppose we are given a probability distribution that has a mean if 14 and a standard deviation of 0.2.

Use the Chebyshev inequality to find a lower bound estimate of the following probabilities:

1. The probability that the outcome will lie between 12 and 16

1. The probability that the outcome lies between 12.5 to 15.5
