Mathematics for IGCSE & O level - Probability (Section 6 - No. 50)
Two dice are rolled. What is the probability of rolling a double (both dice show the same number)?
1/6
1/12
5/36
1/36
説明
There are 6 possible doubles: (1,1), (2,2), (3,3), (4,4), (5,5), and (6,6). Out of a total of 36 possible outcomes (6 * 6), this gives a probability of 6/36 or 1/6.
