In: Statistics and Probability
suppose that you are in a class of 18 students and It
is assumed that 15% of the population is left handed.
a. compute probability that exactly 5 students are left handed( 3
decimal places)
b. probability that at most 4 students are left handed (3 decimal
places)
c. probability that at least 6 students are left handed (3 decimal
places)
Solution:- Given that n = 18, p = 0.15
a. P(X = 5) = 0.0787
b. P(X <= 4) = 0.8794
c. P(X >= 6) = 0.0419
