Step-by-step explanation:

Consider the provided information.

In a raffle where 2000 tickets are sold for $2 each,

One first prize of $400 and one second prize of $200 will be awarded.

Suppose you bought a ticket for $2 and win first price, Then the gain will be: $400-$2=$398

Suppose you bought a ticket for $2 and win second prize, then the gain will be:

$200-$2=$198

Suppose you bought a ticket for $2 and you got nothing, the the loss will be -$2.

The probability of getting first prize is:

Because only one person is selected for first prize out of 2000.

The probability of getting nothing is:  

Hence the expected value is:

Hence, the expected value is -$1.7
