Chapter: Statistics and Probability
What is P(G | T̅) equal to?
Explanation:
n(G ∩ T̅) = 36, n(T̅) = 36 + 27 = 63
∴ p(G | T̅) = p(G ∩ T̅) / p(T̅)
= 36/63 = 4/7
Consider the following data for the next three
(03) items that follow:
There are 90 applicants for a job. Some of them
are graduates. Some of them have less than
three years experience.
Let G be the event that the first applicant
interviewed is a graduate and T be the event that first applicant interviewed has at least
3 years experience.
What is P(G ∩ T̅) equal to?
Explanation:
n(S) = 90
G → Graduate
T → At least 3 years experience
∴ n(G ∩ T̅) = 36
∴ p(G ∩ T̅) = 36/90 = 2/5
