Probably explaining it is better......You have to pick 2 people of same gender and 2 of other gender so that you have 4 people for mixed doubles. To avoid same wife-husband combo, pick 4 pairs among 7 pairs and see that 2 wifes and 2 husbands play together (In such case, there won't be a same wife-husband...

Hi, My answer for the question: for question The number of ways that a mixed doubles tennis game can be arranged from 7 married couples if no husband and wife play on the same game. Ans: In mixed double we have four position. 1. First position of a man can be filled with 7 ways as we can select any man out of seven. --- 7 2. Second position we need to select woman and we can select any 6 woman out of seven as we can not select husband of the person at First position. -- 6 3. In third position we can select any one person out of 5. Why because we should have any couple playing the game any of the side. After first position we are remaining with six man, out of which one would be the husband of second position woman, so we have 5 ways for third position. -- 5 4. For fourth position we can select any one woman out of 4. As after second position is filled we are left with five woman. We can select the woman who is the wife of third position Man. So we are left with 4 woman at fourth position. --4 So total possible arrangement would be all combination of these four position : 7*6*5*4=840. Thanks, Amit read less

No. of ways to select 1st team 7 ways to select a male and then 6 ways to select a female= 7*6 = 42 No. of ways to select 2nd team 5 ways to select a male (1 male is selected reducing the options to 6 and since one female is selected which should not be the wife, the options are reduced to 5) and then 4 ways to select female (1 female is selected reducing the options to 6 and since 2 males have been selected who should not be the husband, the options are reduced to 4) = 5*4 = 20 Total no. of ways = 42 * 20 = 840 Now the only thing left is to remove the duplication i.e. team A vs B and team B vs A is the same combination. To remove this duplication, divide the result by 2. Hence answer would be 420. read less
