Problem 1. The probability of getting 9 as the sum when 2 dice are thrown is 1/9.

What is the probability of getting 9 when we throw two dice?

4. What is the probability of getting a sum 9 from two throws of a dice? Explanation: In two throws of a dice, n(S) = (6 x 6) = 36.

What is the probability of rolling a pair of dice?

Since each die has 6 values, there are 6∗6=36 6 ∗ 6 = 36 total combinations we could get.

What are the most likely outcomes from rolling a pair of dice?

Outcome Probability
9 4/36 = 11.11%
10 3/36 = 8.33%
11 2/36 = 5.56%
12 1/36 = 2.78%

Which is more likely rolling a total of 9 when two dice are rolled or rolling a total of 9 when three dice are rolled?

Which is more likely, rolling a total of 9 when two dice are rolled or rolling a total of 9 when three dice are rolled? Answer: 9 = 3+6 = 4+5 = 5+4 = 6+3, — 4 ways to get total of 9 points rolling two dice, so the probability that the outcome is 9 points is: 4/(6*6) = 1/9 = 0.111.

What is the formula of probability?

P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.

What is the probability of getting a prime number from 1 to 100?

The prime numbers from 1 to 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. Hence, the probability of the event that a number chosen from 1 to 100 is a prime number .

What is the probability that when two dice are thrown the result does not add to 7?

If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.

When two dice are thrown simultaneously What is the probability?

We know that the total number of possible outcomes when two dice are thrown is =6×6=36. We know that the probability of any event is the ratio of the number of favourable outcomes and the number of possible outcomes.

What is the probability of getting a doublet when two dice are thrown?

Probability of getting a doublet = 6/36 = 1/6.

What is the probability of rolling a 1 with 2 dice?

Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on.

What is the probability of getting a total of 7 on the two dice?
