Sets A and B have 3 and 6 elements respectively. what can be the minimum number of elements in AUB

1 answer:

8 0

Answer:

Step-by-step explanation:

n(AUB) = n(A) + n(B) - n(AnB)

n(AUB) can have the minimum number of elements if n(AnB) has the maximum number of elements.

n(AnB) maximum = 3

so n(AUB) = 3+6-3 = 6

write 81 $\pi \\$ or 9 $\pi \\$ etc. don't put in 63.62 like answers
