Two dice are thrown simultaneously. What is the probability that the sum of the numbers appearing on the dice is 7?
उत्तर
According to the question,
Two dice are thrown simultaneously.
So, that number of possible outcomes = 36
Sum of the numbers appearing on the dice is 7.
So, the possible outcomes = (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), (6, 1).
Hence, number of possible outcomes = 6
∴ The probability that the sum of the numbers appearing on the dice is 7 = `6/36 = 1/6`
