Answer:
The expected value of the lottery is $80
Step-by-step explanation:
To get the expected value, we have to multiply each outcome by its probability
Then we proceed to add up all of these to get the expected value of the lottery
we have this as ;;
125(0.2) + 100(0.3) + 50(0.5)
= 25 + 30 + 25 = $80

The area of a triangle is calculated using 1/2b*h, where b = the base and h = the height
The area of a rhombus is calculated using pq/2, where p and q equal the length of the diagonals from opposite points.
Answer:
16 square units
Step-by-step explanation:
The area of the large triangle is
A = 1/2 bh
A = 1/2 (9) * 8 = 36
The area of the small triangle is
A = 1/2 bh
A = 1/2 (8) (5) = 20
The difference is the shaded region
A = 36-20 = 16
