Question

Bailey rolls a fair six-sided die. (Fair means that the die has not been tampered with in shape, Weight, Numbers,etc.) 1.what is the sample of this event? 2.is the probability in this event uniform? 3.what is the probability that bailey rolls a 4? 4. What is the probability that bailey rolls a 1? 5. What should the sum of the probability for each element of the sample space be?

Answer 1

The samples space consists of all possibilities. this is a regular die, it has 6 sides, so the sample space is {1,2,3,4,5,6}

Each is equally likely, there is no reason to think that 6 should come up more frequently than say 1, so the probability of each is uniform, meaning there is no bias for one sample event over another.

If each sample is equally likely and the sum of all probabilities must equal to One, then each sample must have 1/6 of a probability, because 1/6 times 6 equals 1

Answer 2

what is the answer for 3 4 5?? i cant figure it out

Answer 3

Everything is here:

For part 3 and 4, since probabilities are equally likely (i.e. uniform) the answer should be obvious -- see last two paragraphs.

The last sentence above answers question 5.
