Answer: There are 13 gamblers who played exactly two games.

Step-by-step explanation:

Since we have given that

Number of gamblers played black jack, roulette and poker = 5

Number of gamblers played roulette and poker = 8

Number of gamblers played black jack and roulette = 11

Number of gamblers played only poker = 12

Number of gamblers played poker = 24

Number of gamblers who played only roulette and poker is given by

8-5=3

Number of gamblers who played only black jack and roulette is given by

11-5=6

Number of gamblers who played only poker and black jack is given by

24-(12+3+5)\\\\=24-20\\\\=4

So, the number of gamblers who played exactly two games is given by

3+6+4=13

Hence, there are 13 gamblers who played exactly two games.
