Is my Answer correct?
To determine the probability in decimal, percent, and fraction form, we need to convert the given descriptions into numeric values.
A) "Cannot happen": This means the probability is 0.
In decimal form: 0
In percent form: 0%
In fraction form: 0/1
B) "Is certain to happen": This means the probability is 1, which represents 100% certainty.
In decimal form: 1
In percent form: 100%
In fraction form: 1/1
C) "Has a '50-50' chance": This means the probability is 0.5, or 50%.
In decimal form: 0.5
In percent form: 50%
In fraction form: 1/2
D) "Will happen about 3 times out of 4": This means the probability is 0.75, or 75%.
In decimal form: 0.75
In percent form: 75%
In fraction form: 3/4
E) "Has 2 chances in 3 of happening": This means the probability is 2/3, or approximately 0.67, or 67%.
In decimal form: 0.67 (rounded to two decimal places)
In percent form: 67%
In fraction form: 2/3
