Question

1 to Out of the numbers 120, one is the selected at random, what is the probability that it is divisible by 8 or 10?

• A. 0.9
• B. 0.2
• C. 0.6
• D. 0.7

Answer 1

The correct option is B 0.2

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 120.

Let the required event be E ( getting a number divisible by 8 or 10 )

n(E) = 24

Therefore, P( getting a club) = n(E)/S

= 24/120

= 2/10 = 0.2
