- We have a bag with 4 white chips and 6 black chips
- Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?
4 white and 6 black
4 + 6 = 10
Choosing the first white chip : 
Since we took one out , now
3 white chips , 6 black chips
3 + 6 = 9
Choosing another white chip :

Answer:
BD = 78
x = 7
Step-by-step explanation:
As we can see, BC plus CD will be equal to BD. That means we can set up the equation 6x+15+3x = 10x+8. First, we combine like terms to get 9x+15 = 10x+8. Then we can subtract 9x from both sides, to get 15 = x+8. We then subtract 8 from both sides to get x = 7. Since x = 7, we can plug in x for the equation given for BD, 10(7)+8. This will come out to 78.
