Question

suppose amy has a bag of colored wristbands and she chooses one without looking. the bag contains a total of 20 wristbands, of which 17 are yellow. complete parts a and b. a. what is the probability of choosing a yellow wristband? p(yellow) = (type an integer or a fraction.)

Explanation:

Step1: Recall Probability Formula

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

Step2: Identify Values

Here, the number of favorable outcomes (yellow wristbands) is 17, and the total number of outcomes (total wristbands) is 20.

Step3: Calculate Probability

Substitute the values into the formula: \( P(\text{yellow}) = \frac{17}{20} \).

Answer:

\(\frac{17}{20}\)
