Question 816307
A true-false quiz has sixteen questions. A student guesses all the answers. (Round your answers to four decimal places.)
(a) Find the probability of getting eleven correct.
Ans: P(x = 11) = 16C11(1/2)^16 = 0.0667
-------------------

(b) Find the probability of getting at least eleven correct.
P(11<= x <=16) = 1-binomcdf(16,1/2,10) = 0.1051
------------------------

(c) Find the probability of getting no more than two correct.
P(0<= x <=2) = binomcdf(16,1/2,2) = 0.0021
