5 trial regions out of 8 total equals a five in eight chance. Exclusive. Same probability no matter what the last spin was.
50-54= 2
55-59= 4
60-64= 3
65-69= 3
I hope this helps But what I did was I counted how many numbers were in between each of the two numbers.
4 and five eights is equal to 4 + 5/8.
You know that the decimal representation of 5/8 is 0.625, so the decimal representations of 4 and five eights will be 4.625.
Im on that to, maybe i can help you !! :)
Calcualte the ratio 32/48=2/3
