I need this one answer.
The Venn Diagram shows the number of bike and skate club members who bike (circle on the left) or skate (circle on the right).
Compute P (S  B) and write your answer as a decimal. P (S  B) = a0 ways.

Best ResponseYou've already chosen the best response.1first, you are asked for a probability the answer must be a number between 0 and 1, it cannot be 6

Best ResponseYou've already chosen the best response.1i actually don't see a 6 anywhere in the diagram but no matter what is the number in the intersection of that diagram (the number in both circles)?

Best ResponseYou've already chosen the best response.1right there are 5 things in \(B\cap S\) meaning i guess 5 people both bike and skate that will be the numerator of the fraction (the top)

Best ResponseYou've already chosen the best response.1now what is the total number in B (the total, not just the 20)?

Best ResponseYou've already chosen the best response.1the 20 is outside of the intersection you have to include the intersection as well

Best ResponseYou've already chosen the best response.1now we can compute the answer

Best ResponseYou've already chosen the best response.1\[P(SB)\]means the probability that you skate GIVEN that you bike there are 25 people who bike of those 5 also skate

Best ResponseYou've already chosen the best response.1make a fraction, put the 5 in the numerator and the 25 in the denominator

Best ResponseYou've already chosen the best response.1ok that looks good since \[\frac{5}{25}=\frac{1}{5}=0.2\]

Best ResponseYou've already chosen the best response.0alright so 0.2 is the answer then correct?

Best ResponseYou've already chosen the best response.1i have a feeling you did not really understand what was going on go back and look at what we did, convince yourself that a) it makes sense and b) it is not that hard yeah 0.2
