Question

Let a and b be two sets containing 3 and 6 elements respectively. find the maximum and minimum number of elements in a u b

Answer 1

Minimum of a u b = 6 elements

For eg. a=(a, b, c), b=(a, b, c, d, e, f) therefore a u b = (a, b, c, d, e, f)

Maximum of a u b = 9 elements

For eg. a=(a, b, c), b=(d, e, f, g, h, i) therefore a u b =(a, b, c, d, e, f, g, h, i)
