Question

You roll a standard number die. What is the probability of rolling a number less than 5?

Answer 1

look at it this way. it is originally 6. you take away 2 (cause you can only roll 1 through 4,) then you have 4/6, which simplifies to 2/3.

Answer 2

probablity is (desired outcomes)/(total possible outcomes)

less than 5
therea er 1,2,3,4
4 number

total possible is 6 since 6 faces
probablity is 4/6=2/3
