# If two dice are rolled what is the probability of getting a sum less than or equal to 4

• (The sum of $2$ only occurs with probability $\frac{1}{36}$ while the sum of $7$ occurs with probability $\frac{6}{36}=\frac{1}{6}$). Your sample space should be the 36 equally likely possible ordered pairs of numbers on the dice. $\endgroup$ – JMoravitz Sep 11 '18 at 19:07
Sep 05, 2020 · Let's see some examples. Let A be the event of getting a number less than or equal to 4 when rolling a dice, and let B be the event of getting an odd number. Now P(A) = 2/3. and P(B) = 1/2. but the probability of A or B does not equal to the sum of the probabilities:

So the probability we want is 6 36 = 1 6. \frac{6}{36} = \frac{1}{6} . 3 6 6 = 6 1 . Note it doesn't matter if we colored the dice or not! We colored them red and blue to emphasize that (for example) 3-4 is considered different than 4-3. (Even when the dice look the same, they are physically different.)

- [Instructor] Pascale Ricketts has invented a game called Three Rolls to 10. You roll a fair six-sided die three times. If the sum of the rolls is 10 or greater, you win. If it is less than 10, you lose. What is the probability of winning Three Rolls to 10? So, there is several ways that you can approach this.

• The odds of not rolling a 1 or 2 with two dice is 35 in 36. The odds of doing that 25 times in a row is (35/36)25 or about 0.4945Note: The odds of not rolling a 1 is zero, so the answer degraded to the odds of not rolling a 2.=====Opinion #2:-- There are 36 possible outcomes when 2 dice are rolled.--

The probability rule of sum gives the situations in which the probability of a union of events can be calculated by summing probabilities together. It is often used on mutually exclusive events, meaning events that cannot both happen at the same time. Both the rule of sum and the rule of product are guidelines as to when these arithmetic operations yield a meaningful result, a result that is ...

By the most basic definition of probability, the probability of a sum of 7 is 6/36 or 1/6.
