If there are 3 red marbles, 2 blue marbles, 4 white marbles and 6 black marbles in a bag. What is the probability of you randomly selecting a black marble ? Help me please

6/15 chance

Step-by-step explanation:

or 40% chance

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
