city donuts recently sold 14 donuts, of which 4 were cream - filled donuts. considering this data, how many of the next 7 donuts sold would you expect to be cream - filled donuts? cream - filled donuts
Answer
Explanation:
Step1: Calculate the proportion of cream - filled donuts
The proportion of cream - filled donuts in the first sale is $\frac{4}{14}=\frac{2}{7}$.
Step2: Use the proportion to predict the number for the next sale
Multiply the proportion by the number of donuts in the next sale. So the expected number of cream - filled donuts in the next 7 donuts is $\frac{2}{7}\times7 = 2$.
