all the runners in a charity race get free t - shirts. so far, 110 people have taken size small, and 154 people have taken other sizes. considering this data, how many of the next 720 shirts claimed should you expect to be size small? shirts

Answer

Explanation:

Step1: Calculate total number of people

$110 + 154=264$

Step2: Calculate proportion of small - size takers

$\frac{110}{264}$

Step3: Calculate expected number of small - size shirts in the next 720

$720\times\frac{110}{264}=300$

Answer:

300
