Problem
Ricky has a bowl with 80 jellybeans in it. There are 16 red, 24 green, 12 yellow, 20 orange, and 8 black jellybeans. Ricky takes one jellybean from the bowl without looking. What is the probability he takes a yellow jellybean? A. \( \frac{1}{80} \) B. \( \frac{1}{12} \) C. \( \frac{3}{25} \) D. \( \frac{3}{20} \) E. \( \frac{3}{17} \)
Solution
Step 1 ：\( P(\text{yellow}) = \frac{\text{Number of yellow jellybeans}}{\text{Total number of jellybeans}} \)
Step 2 ：\( P(\text{yellow}) = \frac{12}{80} \)
Step 3 ：\( P(\text{yellow}) = \frac{3}{20} \)
