```							n(A) = 40% of 10,000 = 4,000n(B) = 20% of 10,000 = 2,000n(C) = 10% of 10,000 = 1,000n (A B) = 5% of 10,000 = 500n (B C) = 3% of 10,000 = 300n(C A) = 4% of 10,000 = 400,n(A B C) = 2% of 10,000 = 200We want to find n(A  only) = n(A)  –  [n(A B) + n(A C)] + n(A BC)= n(A  only) = 4000  –  [500 + 400] + 200 = 4000 –  700 = 3300 Similarly, n(B only) = n(B)  –  [n(A  B) + n(B C)] + n(A  B C)n(B only)  = 2000 - [500+300]+200 = 1400 n(none of A, B and C) = 10,000 - [n(A)+n(B) + n(C) - n (A  B) - n(B C) - n (C A) + n(AB C)]n(none of A, B and C) = 10,000 - [4000+2000+1000 - 500-300-400 + 200]n(none of A, B and C) = 4000
