To solve this you can make a proportion where the matching sides will correspond to each other. It should look something like this:
Now you must cross multiply
10*42 = 15*x
420= 15x
To isolate x divide 15 to both sides
420/15 = 15x/15
28 = x

11.3x + 7.2 = 86.3
11.3x + 7.2 (-7.2) = 86.3 (-7.2)
11.3x = 79.1
11.3x/11.3 = 79.1/11.3
x = 7
7 is your answer
hope this helps
Using it's concept, it is found that there is a 0.2979 = 29.79% probability that they are in chorus, given that they do not play a sport.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, 125 - 78 = 47 members of the band do not play a sport, of which 42 - 28 = 14 are in the chorus, hence the probability is given by:
p = 14/47 = 0.2979.
