For 3(1), I got (632*211)/(6!) for 3(2), my reasoning is that holds the same

Q: For 3(1), I got (6*3*2*2*1*1)/(6!) for 3(2), my reasoning is that holds the same

Yes you are make right approch, I appriciate your work, 1) Probability that no girl sits beside another girl = (6*3*2*2*1*1)/(6!) = 72 /720 = 0.1 2) Probability that no girl sits beside another girl = (9*3*2*2*1*1*C(n=6,r=2))/(9!) = 108 * 15 / 362880 = 0.0045 Probability that no girl sits beside another girl = 0.0045

Question

For 3(1), I got (6*3*2*2*1*1)/(6!)

for 3(2), my reasoning is that holds the same logic from 3(1), yet combine additional 3 boys. Therefore I got (9*3*2*2*1*1*C(n=6,r=2))/(9!)

Did I make a right approach? If not, could you please enlighten me? Thank you!

3. (1)There are 6 chairs around a table. A group of 3 boys and 3 girls take the seats randomly. What is the probability that no girl sits beside another girl? (2)There are 9 chairs around a table. A group of 6 boys and 3 girls take the seats randomly. What is the probability that no girl sits beside another girl?

Explanation / Answer

Yes you are make right approch, I appriciate your work,

Probability that no girl sits beside another girl = (6*3*2*2*1*1)/(6!) = 72 /720 = 0.1

Probability that no girl sits beside another girl = (9*3*2*2*1*1*C(n=6,r=2))/(9!)

= 108 * 15 / 362880

= 0.0045

Probability that no girl sits beside another girl = 0.0045
