over the past few months, brody has eaten 3 glazed donuts and 6 other donuts. considering this data, how many of the next 3 donuts brody eats would you expect to be glazed donuts? glazed donuts
Answer
Explanation:
Step1: Calculate the proportion of glazed donuts
The total number of donuts eaten is $3 + 6=9$. The proportion of glazed donuts is $\frac{3}{9}=\frac{1}{3}$.
Step2: Predict the number of glazed donuts
We expect the proportion to hold for the next 3 donuts. So the expected number of glazed donuts is $\frac{1}{3}\times3 = 1$.
