Expected value = Sum of Probability * Cost of each ice cream.
Expected value
= 50%* $1.20 + 30%* $2.00 + 2<span>0%* $3.50
</span>
= 0.50* $1.20 + 0.30* $2.00 + 0.2<span>0* $3.50
</span>
= $1.90
Expected value of the cost of one ice cream = $1.90
Use ur calculator ..........
Remark
As long as the representation shows the numbers come one after another, you can get x to be anything.
Givens
x Can be the second number
x - 1 Can be the first number
x + 1 Can be the third number
x + 2 Can be the fourth number
Equation
x + x + 2= 132
Solution
2x + 2 = 132
2x = 130
x = 65
So the 4 numbers are 64 65 66 67
Check
The second and fourth numbers added together = 65 + 67 = 132
