Probability

Let X be a random variable with distribution.


.tg {border-collapse:collapse;border-spacing:0;}
.tg td{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px;
overflow:hidden;padding:10px 5px;word-break:normal;}
.tg th{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px;
font-weight:normal;overflow:hidden;padding:10px 5px;word-break:normal;}
.tg .tg-baqh{text-align:center;vertical-align:top}

x	\(-\)2	\(-\)1	3	4	6
P(X = x)	\({1 \over 5}\)	a	\({1 \over 3}\)	\({1 \over 5}\)	b

If the mean of X is 2.3 and variance of X is \(\sigma\)², then 100 \(\sigma\)² is equal to :
