When calculating probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability that a randomly chosen cube is red we will use the Probability Formula.
P=Favorable Outcomes/Possible OutcomesIn the bag, there is a total of 6 red, 4 yellow, 3 blue, and 1 green cubes. The sum of these values is the number of possible outcomes.
6+4+3+1= 14 cubes
Out of these, 6 are red, which is the number of favorable outcomes. Now we have enough information to calculate P(red).
