Out of a group of 10 contestants, 2 are to be selected at random. What is the maximum number of male contestants possible if the probability that both selected contestants are male is less than 10% ?  Choose the correct choice from the following answers:
A) 0	B) 1	C) 2	D) 3	E) 4
Let n be the number of man. Probability = n/10 * (n-1)/9= n(n-1)/90.   For the probability to be less than 10%, n(n-1) &lt; 9.   Maximum number that satisfies this condition is 3. For 4, it is &gt; 9. Hence the answer is 3.
