let A and B are two sets such that n(A)=4,n(B)=7 ,then find the maximum number of elements in A union B |
|
Answer» Hello, Step-by-step explanation: n(A△B)=n(A∪B)−n(A∩B) for n (A \triangle B)tobemax.n (A \cap B)=0$$ We know, that n(A∪B)=n(A)+n(B)−n(A∩B)=15+25−0=40 ⇒n(A△B) max =40−0=40 For minimum value of n(A△B) n(A∪B) should be MIN, n(A∩B) should be max. n(A△B) min =25−15=10 So. value of n(A△B)=n(A∪B)−n(A∩B) lies om the set 10,11,12,......,3,9,40 Now, when n(A△B) is max. i.e. when n(A∪B)=40 & n(A∩B)=0 If we decrease n(A∪B) by 1 then n(A∩B) Will increase by 1 n(A△B)=39−1=38 Similarly on for the decrease of 1 you will get in (A△B) as 36 and 30 so on. Hence Range of n(A△B)=10,12,14,16,18,20,......,38,40 =16 values n(A) = 4 n(B) = 7 n(AUB) = n(A) + n(B) - n(AnB) let n(AnB) = 0 n(AUB) = 4 + 7 = 11 Hence:AUB=11 Thank You:) |

Answer» Hello, Step-by-step explanation: We know that if a polygon has ‘n’ sides, then it is DIVIDED into (n – 2) triangles. We also know that, the sum of the angles of a triangle = 180°. Therefore, the sum of the angles of (n – 2) triangles = 180 × (n – 2) = 2 RIGHT angles × (n – 2) = 2(n – 2) right angles = (2n – 4) right angles |
