Answer:
C. 0.42
Explanation:
Probability = Possible outcome/Total outcome
Probability value always lies between 0 and 1.
According to the table, the total number of boys that has no job will be our POSSIBLE OUTCOME and the total number of responses will be the TOTAL OUTCOME.
Possible outcome = 42
Total outcome = 100
Probability that the student is a boy who has no job = 42/100
= 0.42
