Ответ:
15,136 hands off with cards contain exactly three queens and three jacks.
Step-by-step explanation:
The order in which the cards are chosen is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
Standard deck:
4 queens and 4 jacks.
The other 52 - 8 = 44 cards are neither queens nor jacks.
Wow many hands off with cards contain exactly three queens and three jacks?
3 queens from a set of 4.
3 jacks from a set of 4.
2 other cards(not queens neither jacks) from the other 44. So
15,136 hands off with cards contain exactly three queens and three jacks.
