## Decision Tree Problem

Hey guys, small doubt with regards to a decision tree.

High: 0.3 $450,000 per annum for two years Medium: 0.4$550,000 per annum for two years
Low: 0.3 \$480,000 per annum for two years

So, in this question, the profit is given for TWO years. So how does this affect my calculation of the expected value?
