Answer
There are about $2.6$ million cases of credit card fraud out of $10$ million cases of identity theft in 2008.
Work Step by Step
First, we need to identify the relative frequency of credit card fraud out of identity theft.
The 'credit card fraud' bar reaches about one-fifth of the way from $0.25$ to $0.30$ line value. Thus, it would be said that the relative frequency of credit card fraud is about $0.26$.
In other words, about $26\%$ of identity thefts occur in the form of credit card fraud.
Now, as to the number of credit card fraud out of $10$ million cases of identity theft in 2008, we need to figure out $26\%$ of $10$ million equals which value.
$$\frac{26\%\times10,000,000}{100\%}=2,600,000$$
So there are about $2.6$ million cases of credit card fraud out of $10$ million cases of identity theft in 2008.
