At 13:03 , why did you put 23 and 65 without the parentages?

[@MrHelpfulNotHurtful]

@@BVB09_rose Did you mean parentheses? Parentheses would not change the answer. You can put them if you want. I’m not sure why you thought they were necessary.

[@BVB09_rose]

@MrHelpfulNotHurtful No I actually meant percentage cuz like didn't they say 23% and 65 % so why didn't we put them in the AROC equation?

[@MrHelpfulNotHurtful]

@ I see. The data is given in terms of percentage like 23 percent. You have a choice to leave the percent in the description at the end or to convert all the numbers to decimals. I chose to leave the word percent in the description at the end like units. It’s the same as when we are given data in thousands like 65 thousand and 23 thousand. It is your choice whether to use 65 and 25 and leave the word thousand in the description as part of the units or you can actually write 65,000. Either is correct.
