Question 985490: At a particular uni it has been found that 20% of the student withdraw without completing the introductory statistics course. Assume that 20 students have been selected.
1) what is the probability that exactly two will withdraw?
2)what is the probability that fewer than seven students will withdraw? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Probability that fewer than seven is 0.998 from table
Probability of 2 exactly is
20C2 (0.1)^2*(0.9)^18=0.2852
