 Option 'a' is correct.                      

Step-by-step explanation:

Since we have given that

Total number of students = 200

Number of females = 110

Number of students under the age of 21 years of age = 125

Number of males under the age of 21 years or older = 45

So,  it becomes

                              Males            Females    Total

21 years                     45                80              125

21 years or older       45                30              75

Total                          90              110               200

So, Probability that a female student age 21 or older is selected is given by

Hence, Option 'a' is correct.
