Answer:
$42.5 billion
Explanation:
the expected value formula = ∑ (valueₙ x probabilityₙ)
expected value = (low value x probability of low value) + (most likely value x probability of most likely value) + (high value x probability of high value)
= ($5 billion x 20%) + ($45 billion x 70%) + ($100 billion x 10%) = $1 billion + $31.5 billion + $10 billion = $42.5 billion
