Explanation / Answer

Q2) P( Not green) = 175/200 = 0.8750

Option A is Correct

Q3) P( Blue or black) = 55/200 = 0.275

Option C is Correct

Q4) P( First two are red and third is green) = (120/200)*(120/200)*(25/200) = 0.045

Option B is Correct

Q5) P( at least one blue) = 1-P( No blue)

P( at least one blue) = 1-(175/200)*(175/200)*(175/200)

P( at least one blue) = 0.33

Option C is Correct
