Describe the difference between events that are certain, likely, unlikely, or impossible.

Certain would be 100% of the time, likely is anything greater than 50% of the time, unlikely is anything less than 50% of the time, and impossible is anything that has a 0% chance of occuring.

There are 200 tiles in a bag. Each tile has one letter on it. Kele selects a tile at random, writes down the letter, and puts the tile back. He does this 5 times. He selects the letters B, A, E, R, and S.   Use Kele’s results to predict how many consonants (not vowels) he will select in the next 20 trials. Show your work.

Marvin selects a rubber ball from a bag at random, records the color, and replaces it. After 15 trials, the experimental probability of selecting a red ball is 715 , selecting a yellow ball is 15 , and selecting a green ball is  13. On the 16th trial, Marvin selects a purple ball. What is the experimental probability of selecting a yellow ball now?
