b.What is the probability that you roll "doubles" that is, both dice have the same number on the upper face?
c. What is the probability that both dice show an odd number?
Answers
there are 6 possibilities on each dice. Therefore 6 x 6 = 36 possible outcomes.
What is the probability that the sum of the number of dots shown on the upper faces is equal to 7?
1,6 2,5 3,4 4,3 5,2 6,1 there are 6 possible ways to get 7
6/36 = 1/6 = .1666...
What is the probability that the sum of the number of dots shown on the upper faces is equal to 11?
5,6 6,5 there are 2 possible ways to get 11
2/36 = 1/18 = .0555...
What is the probability that you roll "doubles" that is, both dice have the same number on the upper face?
1,1 2,2 3,3 4,4 5,5 6,6 there are 6 possible ways to get doubles
6/36 = 1/6 = .1666...
What is the probability that both dice show an odd number?
1,1 1,3 1,5 3,1 3,3 3,5 5,1 5,3 5,5 there are 9 possible ways that both dice show an odd number
9/36 = 1/4 = .25
Final answer:
The probability of getting a sum of 7 when two fair dice are tossed is 1/6. The probability of getting a sum of 11 is 1/36. The probability of rolling doubles is 1/6. The probability of both dice showing an odd number is 1/4.
Explanation:
a. Probability of sum equal to 7:
When two fair dice are tossed, there are a total of 36 possible outcomes, as each die has 6 possible outcomes. Out of these, there are 6 outcomes that result in a sum of 7: (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1).
Therefore, the probability of getting a sum of 7 is 6/36 = 1/6.
Probability of sum equal to 11:
There is only one outcome that results in a sum of 11, which is (5,6) or (6,5). Therefore, the probability of getting a sum of 11 is 1/36.
b. Probability of rolling doubles:
When rolling two dice, there are 6 possible outcomes that result in doubles: (1,1), (2,2), (3,3), (4,4), (5,5), and (6,6). Since there are a total of 36 possible outcomes, the probability of rolling doubles is 6/36 = 1/6.
c. Probability of both dice showing an odd number:
Since each die has 3 odd numbers (1, 3, and 5), the probability of both dice showing odd numbers is (3/6) * (3/6) = 9/36 = 1/4.
