The probability of students participating in Band also participating in Track is 9/33. Statement B is correct about probability.
What is probability?
Probability can be defined as the ratio of the number of outcomes in a set of equal outcomes of the event to the total number of possible outcomes.
Given that at Mountain High School, the students were surveyed about their participation in the band (B) and track (T). The results of the survey are shown in the Venn diagram. Circles B and T intersect. Circle B contains 24, circle T contains 31, and the intersection contains 9. Number 14 is outside of the circles.
We can write this as given below.
B = 24, T = 31, B+T = 9, N = 14
The probability of students who participated in B also participated in T is calculated as given below.
P = outcome of B+T / (outcome of B + outcome of B+T)
[tex]P = \dfrac {(B+T)}{B + (B+T)}[/tex]
[tex]P = \dfrac { 9}{24+9}[/tex]
[tex]P = \dfrac {9}{33}[/tex]
Hence we can conclude that the probability of students participating in Band also participating in Track is 9/33. Statement B is correct about probability.
