in her geology class, nora learned that quartz is found naturally in a variety of colors. noras teacher has a giant box of colorful quartz pieces that he and his students have collected over the years. nora picks a piece of quartz out of the box, records the color, and places it back in the box. she does this 18 times and gets 3 purple, 2 yellow, 5 white, and 8 pink quartz pieces. based on the data, what is the probability that the next piece of quartz nora picks will be yellow? write your answer as a fraction or whole number.

Answer

Answer:

$\frac{1}{9}$

Explanation:

Step1: Identify total number of trials

Total number of picks = 18

Step2: Identify number of favorable outcomes

Number of yellow - colored picks = 2

Step3: Calculate probability

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{2}{18}=\frac{1}{9}$
