The "expected value of a ticket" is the probability of being drawn multiplied by the earnings associated to being drawn.
($1 is the price of the ticket which of course can be different).
So in this case probability is 1/2000 and the earnings would be valued $1000 (value of the plasma TV).
The expected value is 1/2000*1000=1000/2000=$0,5
This means you should not buy a $1 ticket to play except if this really brings you LOTS of amusement ;)
Answer:
C
Step-by-step explanation:
Plug in -3 for x: y = -(-3)²+3 = -9+3 = -6 (-3,-6)
plug in 0 for x: y = =(0)² + 3 = 3 (0,3)
plug in 3 for x: y = -(3)² + 3 = -9+3 = -3 (3, -6)
