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>

Since OC=8 and OC=OF, then OF=8
OEF is a right triangle, so we can find EF using
Now, observe that triangles OEF and OFG are congruent: they are both right triangles, OF is common, and OE=OG because they're both radii.
So, we have
