Continuing with the family from the preceding question,what is their expected utility?
A) $.8 \sqrt { 10 } + .2 \times \sqrt { 2 }$
B) $.8 \times \sqrt { 10 }$
C) $\sqrt { 8 }$
D) $\sqrt { 2 }$

To calculate the expected utility, we multiply the probability of each outcome by its utility and sum them up. 
Expected utility = (.8)(√10) + (.2)(√2) = 0.8√10

The best choice for the family would be to choose option A since it has the highest expected utility of 0.8√10.
