What is the probability of rolling a 7?
For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 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.
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.

|Conditional Probability||P(A | B) = P(A∩B) / P(B)|
|Bayes Formula||P(A | B) = P(B | A) ⋅ P(A) / P(B)|
What is the probability of rolling an odd number?
The probability when rolling a regular six-sided dice that the score is an odd number is three-sixths or three out of six.

What is the probability of flipping tails and rolling a six?
: When you flip a coin there are two possible outcomes (heads or tails) and when you roll a die there are six outcomes(1 to 6). Putting these together means you have a total of 2×6=12 outcomes.
What is the probability of rolling a number between 1 and 6 exclusive?
Answer: If you mean strictly between (meaning not 1 or 6), then you have four favorable choices (2, 3, 4, 5) out of six possible outcomes (1, 2, 3, 4, 5, 6). Therefore your probability is 4/6=2/3. If it’s not strictly between 1 and 6, then any dice roll will give you a 1, 2, 3, 4, 5, or 6.
