frozen [14]

There are 9C_3 ways to select 3 from 9.

There are 5C_3 ways to select 3 men from 5 men and 4C_3 ways to select 3 women from 4 women.



If all three selected are men, then no woman was selected, and we have

5C_3 \times 4C_0 ways we can do that.



1)



P(All -3 -are -men)=[tex]\frac{5C_3 \times 4C_0}{9C_3}=\frac{5}{42}





2) If all 3 are women then no man was selected, and we have

5C_0 \times 4C_3 ways we can do that.


P(All- 3- are- women)=\frac{5C_0 \times 4C_3}{9C_3}=\frac{1}{21}



3) If 2 men and 1 woman were selected, the we have 5C_2\times 4C_1 ways we can do that.


P(2 -men -1 -woman)=\frac{5C_2\times 4C_1}{9C_3}=\frac{10}{21}




4) If 2 women and 1 man is selected, then we have  5C_1 \times 4C_2

P(2- women- 1 -man)=\frac{5C_1\times 4C_2}{9C_3}=\frac{5}{14}
