How to explain it
- A double bar graph shows two sets of data side by side.
- Read the scale first, then compare the bar heights.
- Probability tells how likely an event is: from impossible to certain.
Example: A bag has 3 red and 1 blue marble. How likely is it that you draw red? There are 4 marbles in all. 3 of the 4 are red. Answer: 3 out of 4 (likely)
Question 1
You pick one marble from this bag without looking. What is the probability that it is yellow?
🔵🔵🔵🔵🟢🟢🟡🟡🟡🟡🟡- 1/3
- 6/11
- 5/12
- 5/11
5/11
Hint: Probability = number of yellow marbles ÷ total number of marbles.
