Create a tree diagram showing that you have adidas , nikes and jordans . the colors of the shoes come in red, white and black . what is the probability of you picking black nikes?

The Probability of picking Black Nikes  = 1/9

Step-by-step explanation:

From the Tree Diagram, we can see that the shoes have three branches with three different Brand of shoes (Nikes, Adidas, Jordans)  and each having three different colors (White, Black, Red). So when we have to find the Probability of choosing black Nikes we have only one way of picking Black Nikes. So its Probability will be equal to the no of ways black Nikes chosen divided by the no of total outcomes.

No of outcomes =9        

Because I have Adidas, Nikes, and Jordans. The colors of the shoes come in red, white and black

The probability of picking black Nikes will be  P=1/9

b.an increase in a causes b to decrease

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
