Step-by-step explanation:
Experimental probability represents probability based on an experiment conducted. In the question, it states 40 marbles were drawn and the graph shows that yellow was drawn 10 times. Thus, the experimental probability is ![\frac{10}{40}=\frac{1}{4}=\boxed{25\%}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B40%7D%3D%5Cfrac%7B1%7D%7B4%7D%3D%5Cboxed%7B25%5C%25%7D)
So, let's say that I have 3 bills: a 50 dollar bill, a 100 dollar bill and 1 dollar bill.
I need to buy 9 pens for my friends, and each of the pens costs 4.34 dollars.
I want to know if I can just take the 50 dollar bill, since I'm not too comfortable to carry the 100 dollar bill the whole day.
A quick estiate tells me that 10 times 5 is 50, and since both numbers are less, then in fact, 50 dollar bill will be enough!
