In this question, we're given that there are 15 ,000 employees.
00:04
63 % are male.
00:06
24 % of the employees earn more than 30 ,000 a year.
00:11
And 19 % are male and earning more than $30 ,000 a year.
00:18
Let m be the event of a male and key be the event of employee earning more than $30 ,000 a year.
00:34
In part a, we want to find that the probability that an employee is a male, so we're finding the probability of m, and that is 63%, so it's 0 .63 in decimal.
00:50
In part b, we want to find the probability of an employee earning more than $30 ,000 a year, so that is finding p, t.
01:00
So t is, probability of this t is 24%, so that is, that is, 0 .24.
01:10
In c, we want to find the probability of employee being a male and earning more than $30 ,000 a year.
01:16
Now, this would be finding probability of m and t.
01:23
N is intercept.
01:26
In probability, intersection is n, union is all.
01:32
So m intersect t, that is actually 19%, 19 % over here, so it's 0 .19.
01:42
In part d, we want to find the probability that the employees mail or earning more than $30 ,000 a year...
