To find the expected number of years of college attended The following formula is used:
$$E(X)=\sum_{}^{}xp(x)$$
|dw:1365587907813:dw|
$$E(X)=(0\times \frac{7}{52})+(1\times \frac{6}{52})+(2\times \frac{7}{52})+.......+(5\times \frac{14}{52})$$
Can you now plug in the missing terms and find the value of E(X)?
