Answer 2

3/5  , 0  , 9/25 are probabilities

Step-by-step explanation:

18 - 29       3

30 - 39      27

40 -49       37

50 - 59      8

Total        75

40 or more than 40 years old   Mean 40-49 & 50 - 59

= 37 + 8 = 45

Probability = 45/75  =  3/5

b. Above 60 years of age - None Zero

Probability = 0

e lying between 30-39 years - 27

Probability = 27/75  =  9/25
