What this lesson shows
A bag of 3 red and 1 blue marble: red is likely, blue unlikely, green impossible. Blue's probability is 1 out of 4, written 1/4.
The worked example
The lesson works this one step by step: 3 red and 1 blue marbles: blue. Then your kid tries one like it on paper.
The steps
- Probability: that color out of all
- More than 1 half: likely
- Less than 1 half: unlikely
- None in the bag: 0, impossible
Helping at home
Count the marbles of the color, then all the marbles. The fraction is that color out of all of them. Your kid compares it with 1 half: more is likely, less is unlikely, none is impossible.
If your kid gets stuck
That color out of all the marbles.
