PLZZZZ JUST HELPPP MY IM CRYINGGG HELP
At a fair, each person can spin two wheels of chance. The first wheel has the numbers 1 and 4. The second
wheel has the letters M, A, T, H.
List all the possible outcomes of the
compound event.
What is the probability of spinning a 1 on
the first wheel?
What is the probability of spinning a T on
the second wheel?
If you spin both wheels, what is the
probability that you get either a 1 or a T?
If you spin both wheels, what is the
probability of getting a 1 and a T?

Please don't cry. There's no crying in math.

Wheel 1: 1 2 3 4 Wheel 2: M A T H

Compound Outcomes: 1M 1A 1T 1H 2M 2A 2T 2H 3M 3A 3T 3H 4M 4A 4T 4H

A 1 on wheel 1 is one of four equally likely possibilities.

P(Wheel1=1) = 1/4

There's one T out of 4 letters on wheel 2.

P(Wheel2=T) = 1/4

Just going through our list of 16, I count 7 with a 1 or T, namely 1M 1A 1T 1H 2T 3T 4T. So

P(1 or T) = 7/16

There's only one way to get a 1 and a T out of the sixteen, namely 1T.

P(1 and T) = 1/16
