We roll a cube numbered 1 through 6 once. We want to find the probability that a number less than 3 or an odd number shows on the top face of the cube. To do so we will use the theoretical probability.
P=Favorable outcomes/Possible outcomesThe cube is numbered 1 through 6, so we know that the number of possible outcomes is equal to 6.
Let's find the number of favorable outcomes.
1 2 3 4 5 6
There are exactly 4 number that are less than 3 or an odd number. We are ready to calculate the desired probability.
