Question

In a large university the probability that a student is left handed is 0.08. A sample of 150 students is randomly selected from the university. Let k be the expected number of left-handed students in this sample. 2a. Find k. 2b. Hence, find the probability that exactly k students are left handed; 2c. Hence, find the probability that fewer than k students are left handed.

Step 1

Find k: The expected number of left-handed students in the sample can be found by multiplying the probability of a student being left-handed by the total number of students in the sample. k = (probability of left-handed) * (number of students in the sample) k = Show more…
