An experiment consists of rolling two dice, let E1= “The sum of the numbers is greater than 7” and E3= “The numbers on the two dice are equal”. a. Are E1 and E3 mutually exclusive? b. What are the odds of rolling a pair with the same number on the faces?
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.

What total sum can you expect in rolling a fair dice 20 times Do the experiment, repeat it a number of times, record how the sum varies. Remember the mean of x is also the expectation of x.
help please
Consider the probability experiment of rolling two 6-sided dice, and the associated random variable X = sum of the two dice. () (3 points) See the OpenLab poet which includes the sample space for this experiment, and gives part of the proba bility distribution of Complete the exercise by filling in this table to get the full probability distribution of X Sum of the two dice, Outcomes in the event (X=;} Probability PCX-23) 1/36 = 0.0278 3 {(1,2),...
