A. The probability that you would select a black marble is 10/100. Which is also 1/10.
B. It would be 10/60. Which is 1/6.
For the first you count how many black marbles are in the jar total? There is 10. Which means 10/100.
For the second the red marbles doesn’t count so now we have only 60 marbles in the jar. 10 of those marbles are still black.
