You asked: What is the probability of a dice showing 1 or 6?

What is the probability of a dice showing a 1 or 5?

Hence the probability that at least one shows a 1 or 5 is 1−(2/3)2=5/9.

What is the probability of rolling 1?

The probability of rolling at least one “1” if you roll a dice six times is the same as 1 minus the probability of rolling zero 1s if you roll a dice six times. The probability of not rolling a 1 if you roll a dice once is 5/6.

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 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 a 5 or a 2?

There is a 16 probability of getting a 2 on the first roll and a 16 probability of getting a 5 on the second roll.

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 probability of flipping tails and rolling a six?

Step-by-step explanation:

: 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 getting a sum of 7 when rolling two dice?

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.
