given that an auto parts store is examining how many items were purchased per transaction at the store as compared to their online website

The data is shown below:

             Frequency  Frequency*Midpt  

    Midpt Online Total Online Total

1-3     2      40 147             80 294

4-6         5      60 103            300 515

7-9         8     15 32           120 256

10-12 11       5 18             55 198

           120       300            555 1263

Thus we find total items purchased on line = 555

and total items overall purchased = 1263

Hence the probability that a randomly selected item was purchased online

=\frac{555}{1263} \\=0.4394
