A jar contains only three types of objects: red, blue, and silver paper clips. The probability of selecting a red paper clip is 1/20, and the probability of selecting a blue paper clip is 1/10. What is the probability of selecting a silver paper clip? Choose the correct choice from the following choices:
A) 5/12	B) 1/20	C) 17/20	D) 3/4	E) 11/20
Prob of Red = 1/20   Prob of Blue = 1/10   Prob of Silver = ?   P(Silver) = 1 - P(Red) - P(Blue) ==&gt; 1-1/20-1/10 = 7/12   Ans: 17/20
