Rebecca rolls two number cubes each with sides that are labeled 1 to 6. What is the probability that both number cubes show a 1?
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
1/6 * 1/6 = ?
To find the probability that both number cubes show a 1, we first need to determine the total number of outcomes when rolling two number cubes.
Each number cube has 6 sides, so the total number of outcomes for rolling two number cubes is 6 multiplied by 6, which equals 36.
Next, we need to determine the number of successful outcomes, which in this case is when both number cubes show a 1.
Since there is only one side on each number cube with a 1, the number of successful outcomes is 1 multiplied by 1, which equals 1.
Therefore, the probability of both number cubes showing a 1 is calculated by dividing the number of successful outcomes by the total number of outcomes: 1 / 36.
Thus, the probability is 1/36.
