Answer:
The expected value is $4.35
Step-by-step explanation:
For us to calculate the expected value , we need to multiply each of the given probability by the individual payout value and add
So we have it as;
0.35(1) + 2(0.2) + 5(0.1) + 8(0.2) + 10(0.15)
= 0.35 + 0.4 + 0.5 + 1.6 + 1.5
= $4.35
Model house dimensions
5 cm × 4 cm = 20 cm²
1 cm = 1.5 m
multiply cm by 1.5 = meters
5 × 1.5 = 7.5 m
4 × 1.5 = 6 m
Real house dimensions
7.5 m × 6 m = 45 m²
