Question

Write R code for the following:
Three committees, of sizes 3, 4 and 5, are chosen from 20 people. What is the
probability that persons A and B are chosen for the same committee?

Answer 1

Heya mate...

Yes, you are right. The 3!3! in the second part comes due to the fact that the three chosen people can be assigned the three posts in 3P3=3!=63P3=3!=6 ways. Hope it helps...
