A RECENT SURVEY FOUND THAT THE AGES OF WORKERS IN FACTORY ARE
DISTRJBUTED AS
AGE IN YRS 20-29,30-39 40-49,50-59,60 AND ABOVE
NO OF WORKERS 38,27,86,46,3
IF A PERSON IS SELECTED AT RANDOM FIND THE PROBABILITY THAT THE
PERSON IS

2 UNDER 40YRS
3 UNDER 60 BUT NOT OVER 39YRS

Haresh Rengaraj · Answer

total number of workers = 200
no of workers above 40 yrs= 135
probability= 135/200
=27/40
no of workers under 40yrs=65
probability=65/200
=13/40
no of workers under 60 but not over 39=65
probability= 65/200
= 13/40
