Question

Colin put some buttons on a table. There were 4 blue buttons, 5 red buttons, 7 tan buttons, and 8 white buttons. Colin's cat jumped up and knocked 1 button onto the floor. What is the probability that the button on the floor was blue?
Please help!

Answer 1

4 out of 24 reduced to 1 out of 6 since there are 24 total buttons and 4 are blue. About 16.67%

Answer 2

To find a probability of an event occurring, we need to find how many outcomes are successful. Then divide that number over the total number of outcomes.

In this case, we have the cat knocking 1 button onto floor. We want that button to be blue. Because we have 4 blue buttons, we have 4 different scenarios/outcomes that are successful.

Total number of outcomes is the cat knocking any button onto the floor. Which is [/tex] 4+5+7+8=24[/tex].

When we divide the two: $\frac{4}{24} = \frac{1}{6} = 0.17$ is the probability of cat knocking a blue button onto the floor.
