Exercise

Looking at specific items

Sometimes, you may want to look at specific items rather than looking at overall baskets. From the Online_Retail_clean dataset, you will select baskets containing herb markers. You will be looking at two specific items which have the following description: "HERB MARKER ROSEMARY" and "HERB MARKER THYME". Your task will be to find out the number of baskets containing these items (both individually and in combination).
