The probability of picking two black marbles from a box at random without replacement is 10/91 . the probability of drawing a black marble first is 5/14 . what is the probability of picking a second black marble, given that the first marble picked was black? 4/13 85/182 25/637 45/182

4/13

This is the correct answer! I just took the test! Good luck!!

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
