PROBABILITY
& COMPOUND EVENTS #1
Directions: A compound event represents a series of events happening at the same time, or in order. To calculate the probability of compound events, you can multiply the probabilities of each individual event. Depending on your teacher’s preference, you can write this probability as a fraction or a decimal.
Examples:
EVENT
PROBABILITY
Flipping heads on coin and rolling 5 on a normal die
A 60% free throw shooter making 3 free throws in a row
EVENT PROBABILITY
1) Flipping a coin and getting tails three times in a row __________________
2) Rolling a die and getting a 4 twice in a row __________________
3) Spin a spinner numbered 1-8, and you land on 8 twice in a row __________________
4) A 70% free throw shooter makes two in a row __________________
5) Picking a blue marble three times in a row (replacing it in the bag each time)
from a bag of 4 blues, 4 reds, and 4 greens __________________
6) Pulling a red card from a deck of cards, replacing it, and pulling another red card __________________
7) Picking two numbers from 1-10 and getting a multiple of 3 both times __________________
8) Flipping a coin, rolling a die, then flipping the coin again and getting tails,
a four, then tails again __________________
9) Rolling a die and getting a number other than 4 twice in a row __________________
10) Spin a spinner numbered 1-8 two times, land on two the first time and
land on a factor of 8 the second time __________________
11) A 70% free throw shooter misses two in a row __________________
12) Picking a blue marble, a green marble, and another blue marble (replacing
it in the bag each time) from a bag of 2 blues, 4 reds, and 4 greens __________________
13) Pulling a red card from a deck of cards, replacing it, and then pulling a king __________________
