(b) What is the probability that you either roll a 4 or do not roll a 4? Explain your reasoning. (c) What is the probability that you don’t roll a 4? Explain your reasoning PLEASE HELP

Answer 1

a) the probability that you roll a 4 is 1/6 as here are 6 possible number you could get and 4 is on the die once
b) the probability that you either roll a 4 or do not roll a 4 is 6/6 as rolling a 4 is 1/6 and not rolling a four is 5/6
c) the probability that you do not roll a 4 is 5/6 as there are 6 numbers you could possibly roll and only one of them is a 4 6-1=5 so there is a 5/6 Vance you don’t roll a 4
