Black Blue Red
if I put 4 2 6 5 blue gray Black Red marbles in a bag of what is likely to go to a gray marble?
what is the probability of obtaining a red marble? a blue? a black marble? It's been so long since I've done these .. if I can not remember how to work … HELP!
Add up all the marbles and the likelihood is the number of marbles of that color (positive results) on the total number of marbles (possible outcomes). Total = 17 marbles Grey Probability: 4 / 17 Blue: 2 / 17 Red: 6 / 17 Black: 5 / 17
