# Keno Probability Worksheet

Keno Probability
A popular game of chance in Maryland is KENO. KENO is played with 80 numbers
from which 20 are selected for each game. The player can choose how many numbers
(spots) from 1 to 10 are played on each game. The player marks the slip, pays the KENO
agent and then watches the KENO monitor for the winning numbers for that game. If the
player matches some or all of the winning numbers, the player wins money based on the
payout chart. On the back of the play slip is the KENO Payout Chart. Determine the
probability for some of the payouts from the chart. Some of the problems are started to
help you in understanding the pattern. When necessary, probabilities should be rounded
to the nearest ten-thousandths.
