Solution:-

XP(X) P(x)(x - u)*2 0.20 0.15 0.25 0.15 0.20 0.05 4.6225 1.3225 0.0225 0.005624999999999 0.7225 3.4225 8.1225 18.235 0.9245 0.198375 0.15 0.5 0.45 0.8 0.25 2.15 0.108375 0.6845 0.406125 2.3275 4

10) The expected number of accidents on a given day is 2.15 and the standard deviation is 1.526.

$E(x)=\sum x\ast P(x)$

$E(x)=2.15$

$\sigma =\sqrt{\left \sum[ P(x)\cdot (x-\mu )^2 \right ]}$

$\sigma =\sqrt{\left 2.3275}$

$\sigma = 1.5256$
