Answer:
<em>The probability is 13.33%</em>
Step-by-step explanation:
<u>Probability</u>
The probability of an outcome is defined as the frequency of the number of times the outcome occurs (f) relative to the number of times that it could have occurred (n).
The formula to calculate the probability is:
![\displaystyle P=\frac{f}{n}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20P%3D%5Cfrac%7Bf%7D%7Bn%7D)
Marcus rolled a number cube and the results are recorded in a table where it can be noted that the number five rolled f=24 times. The total number of trials is n=30+45+30+28+24+23=180.
The probability that the next roll is a five is:
![\displaystyle P=\frac{24}{180}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20P%3D%5Cfrac%7B24%7D%7B180%7D)
Simplifying:
![\displaystyle P=\frac{24}{180}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20P%3D%5Cfrac%7B24%7D%7B180%7D)
![\displaystyle P=\frac{2}{15}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20P%3D%5Cfrac%7B2%7D%7B15%7D)
Dividing:
![\displaystyle P=0.1333 = 13.33\%](https://tex.z-dn.net/?f=%5Cdisplaystyle%20P%3D0.1333%20%3D%2013.33%5C%25)
The probability is 13.33%
The "CORRECT" answer is 728/81
I hope this helps.
Have a "AWESOME" day! :)

Step-by-step explanation:
20% u change it to 0.20
0.20 × 65 = 13
Answer:
x^0 y^-3 / x^2 y^-1
= 1 / x^2 y^-1 (y^3) ...because x^0 = 1 and [(y^-1) (y^3)] = y^2
= 1/(x^2 y^2)
