Final answer:
Based on the data provided, we would expect 4 of the next 20 sundaes sold at Dairy Freeze to have nuts, since 2 of the last 10 had nuts.
Step-by-step explanation:
The subject of the question is to predict how many of the next 20 sundaes sold at Dairy Freeze would be expected to have nuts based on the data that 2 of the last 10 had nuts. This is a probability question that involves using past data to predict future outcomes. To solve this, we use the proportion of sundaes with nuts from the last 10, which is 2 out of 10 or 20%, and apply that to the next 20 sundaes. So, we would expect 20% of 20, which is 4 sundaes, to have nuts.
