Let's say there are 1000 people at the game 0.27*1000 = 270 of them are students 0.06*1000 = 60 are students who didn't buy a program 60/270 = 0.222 = 22.2% of the students will not buy a program
So the answer is roughly 22% when rounded to one decimal place
=========================================================== Problem 3
Like with problem 2, we'll assume 1000 people at the game 0.73*1000 = 730 adults 0.42*1000 = 420 adults buy a program approximately 420/730 = 0.5753 = 57.53% of the adults bought a program which rounds to 58%
Answer: 58%
=========================================================== Problem 4
The answer here is simply 63% since this is the percent form of 0.63
The value 0.63 is the total for the "Yes" column
You already found this value by adding up the values in the "yes" column from the original table: 0.42+0.21 = 0.63
=========================================================== Problem 5
x = total number of students and adults combined
look in the "students" row and "no" column. The value of 0.06 is found there.
0.06*x = 35 0.06*x/0.06 = 35/0.06 x = 583.333 which rounds to 583
