Final answer:
To find the probability of selecting a female audience member from the class, we can use the concept of conditional probability.
Step-by-step explanation:
To find the probability that the randomly selected audience member is a female, we can use the concept of conditional probability. The probability of selecting a female student from the class is the number of female students divided by the total number of students in the class, which is 17 females / (17 females + 20 males) = 17/37. The probability of selecting a female from the audience is the number of female audience members divided by the total number of audience members, which is 52 females / (52 females + 68 males) = 52/120. Therefore, the equation to find the probability p that the selected audience member is also a female is:
p = (17/37) * (52/120)
