Answer:
Step-by-step explanation:
Here first open the inner parentheses and use the distributive property,
if you have already covered slopes, you could also get it that way, in fact is simpler that way.
It would stop at 3y+4>11 because the 3y and 4 are unlike terms and can only be divided or multiplied.
blue marbles
y = yellow marbles
Sum = b+y
The <span>chance of a blue marble being drawn first is:
b / (b+y) = 0.55
</span>The <span>chance of a blue marble being drawn first then a yellow next is:
</span>b / (b+y) * y / (b+y-1) = 0.37
This can be solve easily by using a theorem of Bayes
0.37/0.55 = .67 or 67%
