Question

The probability that an individual is left-handed is 0.11. in a class of 29 students, what is the probability of finding five left-handers?

Answer 1

This is a case of binomial probability, with n = 29, p = 0.11 and x = 5.

Using the function binompdf on my Texas Instruments calculator, as follows:

binompdf(29,0.11,5) = 0.117 (answer)
