Me with this question.
this venn diagram shows sports played by 10 students.
let event a = the student plays basketball.
let event b = the student plays soccer.
what is p(a|b)?

Step-by-step explanation:

P(A|B) is the probability of an event A occurring given that another event B has (or will have) occurred.

You first need to check if those two events are mutually exclusive.

Events A and B are NOT mutually exclusive if:

and in that case, events A and B can occur at the same time.

So,

Otherwise, there are mutually exclusive and

wich means

Case 1: events A and B ARE mutually exclusive

with

So

Case 2: events A and B ARE NOT mutually exclusive

So,

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
