The probability of rolling an even number on a die is 3 in 6 or 1 in 2. The probability of rolling a prime on a die is 3 in 6 or 1 in 2, but one of those primes is also even. Simply add the probabilities and you find that the probability of rolling an even number or a prime on a die is 5 in 6.
when rolling a number cube when rolling a number cube what is the probability of rolling an even number or a divisor of 10? rolling an even number or a divisor of 10?
Even probability: 3/6= 1/2 Odd probability: 3/6= 1/2 (a cube has six sides and normally is numbered 1-6)
Since there is only one even prime, 2, the probability of rolling a 2 with one die is 1 in 6.
1/2
the possibles are end less!!
The probability is 3/7.

if a die is rolled.What is the probibil ty that an even number divisible by 3 appears
Possible outcomes of one roll = 6.Probability of an even number on one roll = 3/6 = 0.5 .Probability of an even number on the second roll = 0.5 .Probability of an even number on the third roll = 0.5 .Probability of an even number on all three rolls = (0.5 x 0.5 x 0.5) = 0.125 = 1/8The probability of at least one odd number is the probability of not gettingan even number on all 3 rolls. That's (1 - 1/8) = 7/8 or 0.875 or 87.5% .
If the probability of a event is zero, then the event cannot occur. Therefore, if the probability of an even number is zero, then the probability of an odd number is one.
P(not even) = P(odd) = 3/6=1/3 When rolled 6 times, the probability of an even number not showing up is (1/3)^6 = 1/729.
You carry out an experiment repeatedly. Then the number of times that the selected even occurs divided by the total number of trials is the relative probability for that event.
The probability of getting an even sum on two dice is 18 in 36 or 1 in 2 or 0.5. The probability of doing that three times in a row is 0.53 or 0.125.
You carry out the experiment a large number of times. Count the number of times it was carried out (n). Count the number of times in which the particular outcome occurred (x). Then, the experimental probability for that even is x/n.
Each time you toss the die the probability of rolling an even number is 3 out of 6 or 1/2. So, the probability of tossing three consecutive even numbers is (1/2)3 = 1/8 = 0.125, which is one chance in eight.
The probability is 1/2.
