Solution
The correct option is A 33/100
Probability shows the relationship between two variables in the
form of ratio, percentage or proportion where there the chances of occurrence
of one variable is expressed in terms of the other variable which is usually
sample space.
The
sample space for the event is 100
Let the required event be E ( getting a number divisible by 3)
n(E) = 33
Therefore, P( getting a number divisible by 3) = n(E)/S
= 33/100
= 0.33
