Whats the figure ? to find perimeter the formula is P=2l•2w
-5(x+3)=-4x-15
-5x-15=-4x-15
-5x+4x=-15+15
-1x=0 /-1
x = 0
Answer:
The expected value of the ticket is -$1.10
Step-by-step explanation:
Here, we want to find the expected value of the ticket sales
We start by calculating the probabilities
The probability that someone wins the system is 1/2000
The probability that a person loses the system is 1999/2000
So the expected value will be;
(1/2000 * 1,800) - (1999/2000 * 2)
= 0.9-1.999 = -1.099
To the nearest cent, this is -1.10
