A: We want to select one person who works out three days a week. Our probability is simply 12/80 ~~ 15%

B: At least 4 days a week means 4 days, 5 days, or 6 days.
Hence, we have: (9 + 20 + 8)/80 = 46%

C: At least once a week.
Let's find out how many DO NOT work out and subtract that from our sample space. This means they must work out at least once a week.

(80 - 15)/80 = 81%

Suppose you work for a large coffee distributor that has a secret coffee blend it sells to local stores. You mix the House blend

TiliK225 [7]

The ratio House blend/Organic Free Trade blend is the same and must remain the same.

So, the proportion is:

$\frac{140}{168}=\frac{130}{x}$

Where x is the unknown amount of the Organic Free Trade blend.

So, from the proportion, we have:

$\begin{gathered} 140\cdot x=168\cdot130 \\ 140x=21840 \\ \frac{140x}{140}=\frac{21840}{140} \\ x=156 \end{gathered}$

Answer: 156 pounds of Organic Free Trade blend
