To find out how likely it is to not choose a blue ball from a colorful set, we need to look at how many balls there are and how many of them are blue.
Imagine we have a bag with:
Step 1: Count the Total Balls
First, let's figure out how many balls are in the bag.
We have:
So, we add them up:
Total balls = 3 (Red) + 2 (Blue) + 5 (Green) = 10 balls
Step 2: Count the Non-Blue Balls
Next, we need to find out how many balls are not blue:
Non-blue balls = 3 (Red) + 5 (Green) = 8 balls
Step 3: Understanding Probability
Now, let’s talk about probability. It helps us understand how likely something is to happen.
The formula for probability is:
Probability = (Number of good outcomes) / (Total number of outcomes)
In our case, the good outcomes are the non-blue balls.
So, we have:
Probability of not selecting a blue ball = 8 (non-blue balls) / 10 (total balls) = 0.8
This means:
The chance of not picking a blue ball is 0.8 or 80%.
That tells us that you are very likely to pick a ball that isn't blue!
