Answer

0.412 is the probability that the selected person received a master's degree during the recent year given that they are female.

Steps

Step 1 :Calculate the total number of people who received an advanced degree. This is the sum of all the numbers in the table. Total=26+62+4+10+7+0=109 (in thousands)

Step 2 :The probability that the selected person received a master's degree during the recent year is the sum of the number of males and females who received a master's degree divided by the total number of people. P(Masters)=62+7109=69109=0.633

Step 3 :0.633 is the probability that the selected person received a master's degree during the recent year.

Step 4 :The probability that the selected person is female is the sum of the number of females who received a Bachelor's, Master's, or Doctor's degree divided by the total number of people. P(Female)=10+7+0109=17109=0.156

Step 5 :0.156 is the probability that the selected person is female.

Step 6 :The probability that the selected person is female, given that they received a master's degree during the recent year is the number of females who received a master's degree divided by the total number of people who received a master's degree. P(Female|Masters)=769=0.101

Step 7 :0.101 is the probability that the selected person is female, given that they received a master's degree during the recent year.

Step 8 :The probability that the selected person received a master's degree during the recent year given that they are female is the number of females who received a master's degree divided by the total number of females. P(Masters|Female)=717=0.412

Step 9 :0.412 is the probability that the selected person received a master's degree during the recent year given that they are female.
