Sagot :

Given:

n(L) = 710.

n(M) = 290

n(L ∩ M) = 90

The objective is to find n(L U M).

Explanation:

The general formula to find the required term is,

[tex]n(L\cup M)=n(L)+n(M)-n(L\cap M)[/tex]

On plugging the values in the above formula,

[tex]\begin{gathered} n(L\cup M)=710+290-90 \\ =910 \end{gathered}[/tex]

Hence, the values of the required term is 910.
