den301095 [7]

Answer:

The number of women teachers attending the lecture is 1.

Step-by-step explanation:

Denote the variables as follows:

<em>M</em> = men

<em>W</em> = women

<em>T</em> = teacher

The data provided is:

n (M) = 23

n (W) = 29

n (T) = 4

n (M ∪ T) =  24

Compute the number of men teachers as follows:

n(M\cap T)=n(M)+n(T)-n(M\cup T)

               =23+4-24\\=3

Compute the number of women teachers as follows:

        n(T)=n(M\cap T)+n(W\cap T)

             4=3+n(W\cap T)

n(W\cap T)=1

Thus, the number of women teachers attending the lecture is 1.
