A box contains 6 black marbles and 4 white marbles. What is the probability of selecting a black marble at random from the box?

3/5

Step-by-step explanation:

6 black marbles and 4 white marbles.= 10 marbles

P( black marble) = number of black marbles / total marbles

                            =6/10 = 3/5

6/4 or 1 1/2

Step-by-step explanation:

because there is 6 black marbles and 4 white marbles

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
