Explanation:

Step1: Identify relevant intervals

We need to consider intervals where number of items over 10 is less than 4. These are 0.5 - 1.5, 1.5 - 2.5, 2.5 - 3.5.

Step2: Read frequencies from histogram

For 0.5 - 1.5, frequency is 5; for 1.5 - 2.5, frequency is 9; for 2.5 - 3.5, frequency is 10.

Step3: Sum up the frequencies

$5 + 9+10=24$

Answer:

24
