1/5 as a percentage can be found by setting it equal to x/100. 1/5=x/100
By cross multiplying, you get 5x=100.
Simplify and x is equal to 20 or 20%.
However, we still need to find how many 2s are in the 80 integers.
This can be found by multiplying the percent by the number 80.
So, 0.20(80)=16
Therefore the probability of getting 2 is 16/80 or 20%.
