Irrational, because it is a repeating decimal.
Answer: 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.
