Question
A fair die is a cube with number 1 through 6 on the sides , represented as painted spots. If a fair die is rolled, what is the probability of number 6 landing face up? 1/6 COMPLETE With a fair die, the probability of rolling any number 1 through 6 is the same. If P(1) re epresents the probability of rolling a 1, P(2)the probability of rolling a 2, and so forth, what is the value of: P(1)+P(2)+P(3)+P(4)+ P(5)+P(6) square

The sum of the probabilities of rolling each number on a fair die is 1.
Explicação
## Step 1The problem involves the concept of probability. A fair die is a cube with numbers 1 through 6 on its sides. Each time the die is rolled, each number has an equal chance of appearing. This means that the probability of rolling any number from 1 to 6 is the same.## Step 2The probability of rolling a specific number, such as 1, 2, 3, 4, 5, or 6, is
. This is because there are six possible outcomes when rolling a fair die, and each outcome is equally likely.## Step 3The problem asks for the sum of the probabilities of rolling each number. This can be calculated by adding the individual probabilities together.### \( P(1) + P(2) + P(3) + P(4) + P(5) + P(6) = \frac{1}{6} + \frac{1}{6} + \frac{1}{6} + \frac{1}{6} + \frac{1}{6} + \frac{1}{6} \)## Step 4When these fractions are added together, they sum up to 1. This is because the total probability of all possible outcomes is always 1.
