A sports club has 38 members. They all play either squash or tennis.

Brut [27]

Step-by-step explanation:

Since we have given that

Total number of members in a sports club = 38

Number of women in the club = 14

Number of women play tennis =10

Number of men play tennis = 8

Since they all play either squash or tennis.

Total number of men in the club is given by

$38-14\\\\=24$

So, number of men playing squash is given by

$24-8\\\\=16$

Number of women playing squash is given by

$20-16\\\\=4$

so, the table is shown below :

Men Women Total

Tennis 16 4 20

Squash 8 10 18

Total 24 14 38
