Question

if n(U) = 50 n(a)28 n(b)=30 find greatest value of n(aUb)

Answer 1

n(a n b) = n(a)+ n(b)- n(aub)
50=28+30
50=58
n(aub)=8

Answer 2

Concept Introduction: Sets are a part of interesting mathematics.

Given:

We have been Given:

$n(u) = 50 \\ n(a) = 28 \\ n(b) = 30$

To Find:

We have to Find: The greatest value of

$n(aub)$

Solution:

According to the problem,

$n(aub) = n(a) + n(b) \\ n(aub) = 28 + 30 = 58$

Final Answer: The greatest value of

$n(aub) = 58$
