The probability of getting at least one prime number in two dice is 3/4.
"The probability of getting a prime number in a die is 4/6" Actually there are 3 prime numbers on a die. 2, 3, and 5 are all prime numbers. So this tells you that you have 3 chances it will be a prime number and 3 chances it will not be a prime number. So the probability of getting a prime number on a die would be 3/6 or 1/2.
1 out of 2.
1 in 2.
It is 2/3.
The probability of rolling a six and then a prime on a die is (1 in 6) times (3 in 6), which is (3 in 12), which is (1 in 4), or 0.25
They are equiprobable events. There need not be any other link.The probability of any one of the following outcomes is 0.5: getting head on a toss of a fair coin, getting a red card when drawing a card at random from a regular deck, rolling a prime number of a fair die.
There are 20 numbers from 20 through 39, and 4 of them are prime (23, 29, 31, 37), the probability is 4 in 20 or 0.20.
When a fair die is thrown the probability that a prime number will occur is 2:1
The answer depends on the sum of WHAT!
