Solution

The correct options are
A The probability of getting a male aged 10-20 is 316
D The probability of getting a female is 12

Total number of people in the given locality = 15 + 16+ 9 + 8 + 20 + 12

= 80

Total number of females = 8 + 20 + 12

= 40

Number of males with age 10-20 = 15 and Number of females with age 10-20 = 8

Probability to get a male aged 10-20= Number of favourable outcomesTotal number of possible outcomes

= Number of females with age 10-20Total number of people in the given locality

= 1580

= 316

Probability to get a female aged 10-20= Number of favourable outcomesTotal number of possible outcomes

= Number of females with age 10-20Total number of people in the given locality

= 880

= 110

Probability to get a female= Number of favourable outcomesTotal number of possible outcomes

= Number of femalesTotal number of people in the given locality

= 4080

= 12
