Question

# Assertion : Two dice are thrown simultaneously. There are 11 possible outcomes (2,3,4,5,6,7,8,9,10,11,12) and each of them has a probability 111. Reason : Probability of an event (E) is defined as P(E) =Number of outcomes favourable to ETotal number of possible outcomes.

Solution

## The correct option is D Assertion is false but reason is true. If two dice will be thrown simultaneously then the total number of possible outcomes is 36 and probability of each outcome is not equal to 111. Probability of an event (E) is defined as P(E) =Number of outcomes favourable to ETotal number of possible outcomes. For example, probability of getting an even number on a die when a die is thrown =Number of outcomes favourable to ETotal number of possible outcomes =36 [∵ Here, the number of favourable outcomes will be 3 as 2, 4 and 6 are the possible even numbers ] ⇒Assertion : False ⇒Reason : True
