Suppose Bank of America would like to investigate if the credit score and income level of an individual are independent of one another. Bank of America selected a random sample of 400 adults and asked them to report their credit score range and their income range. The following contingency table presents these results.

	Credit Score
Class	Less than 650	650–750	More than 750
Income < $50,000	30	24	27
$50,000 ≤ Income < $100,000	42	47	38
$100,000 ≤ Income < $150,000	49	35	26
Income ≥ $150,000	27	29	26

The expected number of individuals with income between $50,000 and $100,000 and a credit score less than 650 is ________.
