prob(greater than two) = 4/6 = 2/3
prob(not greater than two) = 1 - 2/3 = 1/3
Caitlyn calculated the probability of the complement of rolling a number greater than 2 on a 6-side number cube. She made her calculation as follows.
Did she make an error? Explain.

Yes, she made an error. Caitlyn should have taken the desired outcomes, rolling a 3, 4, 5, or 6, and divided that by the total possible outcomes. The correct probability would be 4/6, or 2/3.
yes she made an error. The correct prob would be 4/6 or 2/3
* not 2/3 its 1/3 sorry
Yes, she made an error. Caitlyn should have taken the desired outcomes, rolling a 3, 4, 5, or 6, and divided that by the total possible outcomes to get a probability of 4/6, or 2/3. She should have subtracted this probability from 1 to get the complement, which is 2/6, or 1/3.
You are dumb pay attention to class
