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.

The equation is y=2x+1 so plug in 43 for y
43=2x+1
42=2x
21=x!!
Answer:
y-3
Step-by-step explanation:
4(y-3) + 9 - 3y
Use distributive property for 4(y-3)
= 4y-12+9-3y
Then simplify
= 4y-3y-12+9
= y-3
