• Some of the older Khan Academy videos have been replaced by newer ones that are higher quality and more accurately reflect what the SAT is like presently. Comments are kept the same, though. You might find this in a couple cases especially in math, where the comment section is talking about a different problem.
• Why do you take the number of male rap fans out of the male total and not the entire total?
• I have the same question too, but I think it is because the question stated separated by gender. I could be wrong, yet I think that is the reason why.
• yes we talking about ice cream like fr
• why didn't you say 4/10? i thought of it as what's the chance that a male would like rap music out of all the people that like rap music, and not out of all the males, who likes rap music?
the question was worded weirdly.
• The question for your answer would be like: "What is the probability that people who like rap music are males?"
• it stinks that you can't ask questions on the practice questions themselves so I am forced to ask my table data practice related question here:

In one of the table data practice problems there is a table showing gupta flie sample sizes in the years 2001 & 2002 for three different parks ( Lets call them B,F,G )

then it asks for the percentage likelyhood that a gupta fly was selected from parks B or F

But it does not specify the year. I finally just guessed maybe they meant in total, and went with that and I was obviously wrong but they did not ask for the year 2001 specifically so, how was I supposed to know? is there something in the problem I'm missing?
• is the math part of sat this easy bro? like this is a no brainer. i heard the majority are geometry and graphs
• no its not. if you solve the easy part you may score alone 300-250 in math. and tbh its not about sat math being hard rather its about the wide range of topics covered.
• What should be the question for answer to be 4/72?
• A possible question could be:
If a person was randomly selected from the group, what is the probability that a male that likes rap music is selected?
• Why do you take the number of male rap fans out of the male total and not the entire total?
