Step-by-step explanation:
In the probability questions like this one, in order to get the answer,we would use the multiplication rule.
In your questions, we are trying to find the probability of ALL of your friends going to the mall with you.
Lets make it easier for you.
Whenever in probability you can say and, you multiply.
This means that you would try to find if friend 1 and friend 2 and friend 3 will say yes.
That's the same as saying friend 1's probability × friend 2's probability × friend 3's probability
We know that each friend has a 0.70 chance of saying yes.
Using the multiplication rule, we would just multiply 0.7 three times.
[tex]0.7 *0.7*0.7=0.343[/tex]
When you multiply, you should get 0.343.
There is a 0.343 chance of ALL your friends saying yes to go to the mall with you.
0.343 would be your FINAL answer.
