If a die is rolled 3 times what is probability of getting an even number?

The probability of getting an even number on at least one of the 3 rolls is 7/8.


A dice is rolled three times the probability of getting at least one odd number is?

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% .


What is the probability of rolling an even number with 3 dice?

With one roll of three dice, the probability is 7/8.


The probability that an individual is left handed is 0.1 In a class of 30 students what is the probability of finding at least 5 left hander's?

This is a binomial probability distribution. The number of trials, n, equals 30; and the probability of success is p, which is 0.1. In this problem, you want the probability of at least 5, which is the complement of at most 4. We use the complement because we can subtract from 1 that probability and we will have the solution. The related link has the binomial probability distribution table which is cumulative. Per the table, at n=30, p=0.1 and x = 4; the probability is 0.825. Therefore the probability of at least 5 is 1 - 0.825 or 0.175.

What is the probability of getting at least one prime number in two dice?

The probability of getting at least one prime number in two dice is 3/4.


If 20 percent of people who enter store buy something and 3 people enter what is the probability of at least one sale?

The probability of at least one event occurring out of several events is equal to one minus the probability of none of the events occurring. This is a binomial probability problem. Go to any binomial probability table with p=0.2, n=3 and the probability of 0 is 0.512. Therefore, 1-0.512 is 0.488 which is the probability of at least 1 sale.

What is the probability that at least 2 people have the same birth month in a group of 8 people?

Birth months are not uniformly distributed across the year. However, if yo assume that they are, the probability is 0.9536 (approx).


What is the empirical probability of tossing a coin 5 times and obtaining at least 3 consecutive heads?

The empirical probability can only be determined by carrying out the experiment a very large number of times. Otherwise it would be the theoretical probability.
