First spin lands on blue, we notice that 6 sections out of 10 are blue. Ā This is 60%.
Second spin lands on gray, we notice that there are 4 sections out of 10. Ā This is a 40% chance.
In order to find the probability of both spins together, we need to do the math as follows.
Ā
What's 60% of 40%. Ā Or .6 X .4. Ā Or 6/10 X 4/10. Ā It's all the same thing.
If you did the math in either way, you get 24%.
Hope this helps!
