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? Explain.

Answer:

yes

Step-by-step explanation

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.

This is the sample answer I got!!

Sample : 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.

~I hope this helps <3~
