Which statement is true about whether C and Y are independent events? C and Y are independent events because P(C∣Y) = P(Y). C an
d Y are independent events because P(C∣Y) = P(C). C and Y are not independent events because P(C∣Y) ≠ P(Y). C and Y are not independent events because P(C∣Y) ≠ P(C).

My answer:
C and Y are not independent events because P(C∣Y) ≠ P(C).
Probability of C = 110/300 = 0.37
Probability of Y = 75/300 = 0.25
Probability of (C|Y) = 0.37 * 0.25 = 0.0925
As you can see, </span><span>P(C∣Y) is 0.0925 which is not equal to P(C) = 0.37. Thus, C and Y are not independent events. </span><span>
