A boy has a collection of blue and green marbles. The number of blue marbles belong to the set `{2,3,4,…..,13}`. If two marbles are chosen simultaneou

Correct Answer - A::B::C `(a,b,c)` Let the no. of blue marbles is `a` and no. of green marbles is `b` . `:.(ab)/("^(a+b)C_(2))=(1)/(2)` `implies(a+b)(a+b-1)=4ab` `impliesb^(2)-(2a+1)b+a^(2)-a=0` but `b in R implies D=(2a+1)^(2)-4(a^(2)-a)=8a+1` `:....

3. Suppose set \( A \) consists of first 250 natural numbers that are multiples of 3 and set \( B \) consists of first 200 even natural numbers. How many elements does \( A \cup B \) have? (a) 324 (b) 364 (c) 384 (d) 400

Given: n(A)=250              n(B)=200 A={3,6,9,12,.......750} B=2,4,6,8,10.......400} Therefore,A⋂B={6,12,18....396)                   =>n(A⋂B)=396/6=66   n(A∪B)=n(A)+n(B)-n(A⋂B)               =250+200-66              ...
