Q. 11

A die Is tossed twice. Find the probability of getting a number greater than 3 on each toss.

Answer :

We are throwing two dice so,

Sample space S={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),






Sample space contains 36 elements,

Let ,

A= getting a number greater than 3 on first toss




B= getting a number greater than 3 on second toss

B={(1,4),(1,5),(1,6), (2,4),(2,5),(2,6), (3,4),(3,5),(3,6), (4,4),(4,5),(4,6), (5,4),(5,5),(5,6), (6,4),(6,5),(6,6)}

P(AB)=P(getting a number on each toss)

Given that A and B are independent events,
