Question

A has 3 elements and B has 6 elements. The max and min number of
elements in AUB is
(a) 6,3
(b) 9,3
(c) 9,0
(d) 9,6​

Answer 1

Step-by-step explanation:

when we say union then it means we have to club the 2 sets such that every element from both sets come only once for ex

set a=1,2,3

set b=3,4,5,6

then aub is 1,2,3,4,5,6

all elements from both sets written once

so if a set has 3 and 6 elements then minimum elements will be 6

for ex a=1,2,3

b=1,2,3,4,5,6

aub=1,2,3,4,5,6

Hope this helps......
