Question

The probability of picking two black marbles from a box at random without replacement is 10/91 .

Answer 1

The probability of the 2 events are multiplied to get the result 10/91

so we have the relation 5/14 *  x  = 10/91

where x is the probability of drawing the second black

so x =  10/91 * 14/5 =  4/13   answer

Answer 2

Answer:

4/13

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