Assume that 13% of people are left-handed. Suppose 8 people are selected at random. Answer each question about right-handers below.
e) What's the probability that the majority is right-handed?
Homework Answers
| here this is binomial with parameter n=8 and p=0.13 |
probability that the majority isright-handed =P(at most 3 are left handed):
| probability = | P(X<=3)= | ∑x=0x (nCx)px(1−p)(n-x) = | 0.9871 | |
