Question

a bag with 6 marbles has 6 yellow marbles. a marble is chosen from the bag at random. what is the probability that it is yellow? write your answer as a fraction in simplest form.

Explanation:

Step1: Recall Probability Formula

The probability of an event is the number of favorable outcomes divided by the total number of possible outcomes. So, \( P(\text{yellow}) = \frac{\text{Number of yellow marbles}}{\text{Total number of marbles}} \).

Step2: Identify Values

Number of yellow marbles is 6, total number of marbles is 6.

Step3: Calculate Probability

Substitute into the formula: \( P(\text{yellow}) = \frac{6}{6} = 1 \).

Answer:

\( 1 \) (or \(\frac{6}{6}\) simplified to \(1\))
