Answer:
The correct answer choice is D
Step-by-step explanation:
The probabilty is how much there is of the thing you are measuring divided by the total amount. Therefore, these are all the probablities:
White balls: 4/16 or 0.25 or 1/4 or 25%
Red balls: 8/16 or 0.50 or 1/2 or 50%
Black balls: 4/16 or 0.25 or 1/4 or 25%
Based on these probablities, we can now find the correct answer.
D is the correct answer because 8 balls amounts to half the total which means you have a 50 percent chance of picking it and 50 percent chance of not picking it.
