Total number of students:
9+15+8+12=44
Total number of females:
15+12=27
The selection is random, so all students have equal probability of being selected.
So the probability of selecting a female is 27/44. Convert to a fraction and round to the nearest hundredth (i.e. two places after the decimal point).
An introductory psychology class has 9 freshman males, 15 freshman females, 8 sophomore males, and 12 sophomore females. If one student is randomly selected from this class, what is the probability of selecting a female? Round to the nearest hundredths place if a fraction
