What is the probability of rolling a 1 assuming you roll an even number? What is the probability of never rolling a 6 when rolling a 6-sided die 10 times? What is the probability of rolling a 4 or an odd number on a six sided die? What...
For example, the probability of rolling three 2s in a row is: (0.167)(0.167)(0.167) = 0.0046 or 1/216 The probability of rolling an odd number followed by an even number is: (0.5)(0.5) = 0.25 Warning You cannot use this method to solve problems like calculating the probability of ro...
A pair of dice is tossed and the face number of each die is recorded. Assuming the dice are fair, what is the probability of the sum of the die faces showing is even? What is the probability of rolling an odd number on a fair d...
Thus, the probability when rolling one die twice and only gettng the number 6 at the second time would be 56×16=536. (3) There are two cases when finding the sum of the numbers an odd number. 1. The number of the first roll is an odd number while that of the second roll is ...
What is meant by rolling a die? In a random experiment of throwing a die, if the outcome of the throw is 4, then we say that each one of the following happens – Getting 4 Getting aneven number Getting a number greater than 3 ...
Two six-sided dice are thrown. What is the probability that the sum of the two is a prime number? Find the probability of rolling a prime number when an 18 sided dice is rolled? If two dice are rolled, then what is the probability that sum of outcome is prime?
P(3) = number of ways to roll a 3 = 1 number of possible outcomes 6 = 0.167 What is the probability of rolling at least a 3? P(3) = roll 3 or roll 4 or roll 5 or roll 6 = 4 = 2 number of possible outcomes 6 3 = 0.667 What is the probability of rolling an odd number...
For example, getting heads and tails when tossing a coin or rolling a 222 and a 333 on a die. For mutually exclusive events: P(A or B) = P(A) + P(B) If we have an exhaustive list of outcomes, their probabilities sum to 1.1.1. For example, the probability of getting an even ...
Let us look at an example. Example 1: Probability as a Fraction What is the probability of rolling a number greater than 5 on a fair die? Answer There are 6 faces on a fair die. There is only one face with more than 5 dots on it. That is the face with 6 dots. So, we have...
Find the probability of rolling an even total exactly once? A pair of dice is rolled 240 times. What is the probability that a total of 7 occurs: (a) at least 34 times? (b) between 48 and 55 times inclusive? (c) exactly 40 times? What is the probability of rolling a ...
