2) The table shows the sample space for a mathematics class
Sex Freshman Sophomore Junior Senior Total
Female(Fe) 15 5 2 2 24
Male(M) 10 7 6 3 26
Total 25 12 8 5 50
If one student is selected at random from the class, find the probability that:
a) The student is a freshman, P (Fr) = \frac{25}{50} = 0.5
b) The student is female, P (Fe) = \frac{24}{50} = 0.48
c) The student is male and sophomore, P (M and So) = \frac{7}{50} = 0.14
d) The student is either a female or a freshman, P (Fe or Fr) = \frac{24 + 25 - 15}{50}
e) The student is a Junior given he is a male, P (Jr | M) =
