Answer:

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.

Please help on this problem
Harlamova29_29 [7]
Answer: EP is 12 and EO is about 10.91.

To find the length of EP, we can use the Pythagorean Theorem with the 2 legs of the right triangle it would form, EC and CP. CP would be 5 because it is the midpoint of the side.

5^2 + (EP)^2 = 13^2
EP = 12

Now, to find EO, we write and solve another Pythagorean Theorem equation using 12 for EP.

5^2 + (EO)^2 = 12^2
EO equals the square root of 119 or about 10.91.

What is bigger 2/8 or 7/8
Vedmedyk [2.9K]
7/8 would be greater because first, lets see if they have same denominators. Yes, they do! So is 2 or 7 greater? Obviously, 7 is greater. So 7/8 is greater than 2/8. 

OR

2/8 < 7/8
