Question

There are 10 pink marbles and 10 black marbles. Find the probability?
​

Answer 1

50% to pull either a black or pink marble.

Explanation:

The reason for this is due to the fact you have an equal amount of marbles of 2 different colors, so the chance of pulling one marble is not over another unless you remove say 1 pink marble, therefore the black marbles would have a higher percentage of being pulled instead of pink.
