The probability of being left-handed is 0.12. If we sample 25 people at
random, what is the probability that exactly 2 people are left-handed?
how do i tackle this one? please
Have you learned binomial distribution?
There are C(25, 2) ways to choose two people out of 25. (This is the same as , just different notation, easier to type in.) For each of these, the probability is .
