In how many ways can a group of 5 men and 2 women be made out of a total of 7 men and 3 women?
We need to form a group of 5 men and 2 women from:
- 7 men 👨👨👨👨👨👨👨
- 3 women 👩👩👩
Step 1: Choose 5 men from 7 👨💼
We select 5 men from 7. The number of ways to do this is:
(75)=7×62×1=21\binom{7}{5} = \frac{7 \times 6}{2 \times 1} = 21(57)=2×17×6=21
So, there are 21 ways to pick the men. ✅
Step 2: Choose 2 women from 3 👩💼
Now, we pick 2 women from 3:
(32)=3×22×1=3\binom{3}{2} = \frac{3 \times 2}{2 \times 1} = 3(23)=2×13×2=3
So, there are 3 ways to pick the women. ✅
Step 3: Multiply both choices ✖️
Since both choices are independent, we multiply them:
21×3=6321 \times 3 = 6321×3=63
🎯 Final Answer:
The group can be made in 63 ways! 🎊
