Question

A state offers two lottery games, WinOne and PlayBall. Both games cost $2 per ticket.

In WinOne, the player picks a single letter from A to J and a single digit from 0 to 9. If both the letter and the digit match the letter and the digit picked on that day, the player wins $150.
In PlayBall, the player picks a single letter from A to T and a single digit from 0 to 9. If both the letter and the digit match the letter and the digit picked on that day, the player wins $280.

If Mr. Boyle played WinOne lottery 100 times and won twice, what were his net winnings per turn?

A.
$1

B.
$2.5

C.
$3

D.
$4

Answer 1

A. $1

Explanation:

If he played WinOne 100 times, it means that he spent $200. If he won the lottery twice it means that he won $300 in total. We know that the earnings is given by the difference between the money won and the money spent.

Earnings = Won - Spent

Earnings $100.

Now, the net winning per turn is given by the division between the earnings and the number of times played:

Net winning per turn = $100/100 = $1

Therefore, he net winning per turn is $1.
