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. P (less than 5) = StartFraction Numbers greater than 5 over Numbers less than 5 EndFraction = StartFraction 2 over 4 EndFraction Did she make an error?

Answer:yes she made an error. Caitlyn should have taken the desired outcomes, rolling a 3, 4, 5, or 6, and divide that the total possible outcomes to get a probability 4/6 or 2/3. She should have subtracted this probability from 1 to get the complete which is 2/6 or 1/3

Jamya Hood · Answer 2

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.
