Question

a shirt rack contains 5 striped shirts, 8 solid shirts, and 6 polka dot shirts. how many outcomes are there when choosing a shirt from the rack?
○ 3
○ 13
○ 14
○ 19

Explanation:

Step1: Identify the number of each type of shirt

Striped shirts: \( 5 \), Solid shirts: \( 8 \), Polka dot shirts: \( 6 \)

Step2: Apply the addition principle (for counting outcomes of mutually exclusive events)

To find the total number of outcomes (choosing any one shirt), we add the number of each type of shirt. So, \( 5 + 8 + 6 \)

Step3: Calculate the sum

\( 5 + 8 = 13 \), then \( 13 + 6 = 19 \)

Answer:

19
