Two dice are thrown simultaneously. The probability of getting a pair of ACE is
1/36
1/3
1/6
None of these
If A and B are two such events that , then which of the following is true?
P(a) + P(B) = 0
P(A) + P(B) = P(A)P(B/A)
P(A) + P(B) = 2P(A)P(B/A)
None of the above
A die is rolled three times. The probability of getting a larger number than the previous number is
B.
When a die is rolled three times
Then, cardinality of sample space = 63
Now, according to question, the favourable outcomes
= {(1, 2, 3), (1, 2, 4), (1, 2, 5), (1, 2, 6), (1, 3, 4), (1, 3, 5), (1, 3, 6), (1. 4, 5), (1, 4, 6), (1, 5, 6), (2, 3, 4), (2, 3, 5), (2, 3, 6), (2, 4, 5), (2, 4, 6), (3, 4, 5), (3, 4. 6), (4, 5, 6), (2, 5, 6), (3, 5, 6)}
