In an Statistics class 70 of the students are ME majors 12 a

In an Statistics class, 70% of the students are ME majors, 12% are EE majors, and 18% are CEE majors. On a certain day, 23% of the ME majors, 80% of the EE majors, and 50% of the CEE majors attend class. If I call on a student who attends class randomly, what is the probability that she is an EE major?

Please show all steps...

Solution

Let S be the sample space and EE is the space for EE majors.

S= {All students}

n(S) =100 (Say 100 students in college)

n(EE attending class) = 12% (80%)

Probability for EE attending class = 0.096.
