An experiment consists of rolling 2 dice and observing the number that lands on the uppermost surface. Find the probability that the one of the numbers is a 5, given that the sum of the numbers is even.
Explain and answer in decimals please, thank you.
P(one of the number is 5 | sum of the numbers is even)
= P(one of the number is 5 and sum of the numbers is even)/P(sum of the numbers is even)
= 4/18 = 0.2222

A pair of dice is rolled, and the number that appears uppermost on each die is observed. Refer to this experiment and find the probability of the given event.One die shows a 5, and the other is a number less than 2.
A pair of dice is cast, and the number that appears uppermost on each die is observed. Find the probability of the event that the sum of the numbers is either 2 or 9.

Please help me with this problem and give step-by-step instructions. Thank you An experiment consists of rolling a pair of dice 1000 times. Let X be the number of times the sum is 7. Find the standard deviation of X.
An experiment consists of rolling two fair dice and adding the dots on the two sides facing up. Using the sample space provided below and assuming each simple event is as likely as any other, find the probability that the sum of the dots is 9 or 11 Click the icon to view the sample space. The probability the sum of the two die is either 9 or 11 is (Type an integer or a simplified fraction.)

1. Consider the experiment of rolling a pair of dice values showing on the dice. experiment of rolling a pair of dice. Suppose we are interested in the sum of face a. How many simple events are possible? b. List the sample space. c. What is the probability of obtaining a 7? d. What is the probability of obtaining a value of 9 or more? Because each roll has six possible even values (2.4,6,8,10,12) and five possible odd values (3,5,7,9,11),...
