Answer: 0.6
Step-by-step explanation:
Total population of class = 50
There are 27 athletes, and 9 musicians However, 6 of the musicians are also athletes.
Therefore, totals for athletes and musicians are:
27 + 9 -6 = 30
Thus, the probability of choosing an athlete or a musician is 30/50= 0.6
We could also use the formula:
P(A or M) = P(A) + P(M) - P(A and M)
P(A or M)=27/50+9/50-6/50
P(A or M)=30/50=0.6
I hope this helps!
