The experimental probability is found as the average of the results of the experiments. To find the average you can just add the different results and divide by the number of times that the experiment was performed. So, you add (6/20 + 6/20 + 5/20 + 7/20= and divide by 4 (which is the number of times that the experiment was carried out). Applying the properties of the division of fractions, that is equal to [6 + 6 + 5 + 7] / (20*4) = 0.3. <span>Answer: 0.3</span>
In order to find the fraction of the 20 dollars that has been spent, we have to divide the amount spent by the total amount. So 0.65 is the fraction of 20 that is spent.
