Hello!
To find the probability of two events, you need to multiply the probability of all the events that make the compound event. In this case, we need to multiply the probability of selecting urn 1 and selecting a white marble from urn 1.
First, we have two urns, so we have a 1/2 chance of selecting urn 1.
Next, we have 16 total marbles in urn 1. If we have 5 white marbles, this gives us 5/16.
Finally, we multiply the probabilities. 1/2(5/16)=5/32.
Our final probability is 5/32, or about 16%.
I hope this helps!
Simplifying
4w2 + 24w = 0
Reorder the terms:
24w + 4w2 = 0
Solving
24w + 4w2 = 0
Solving for variable 'w'.
Factor out the Greatest Common Factor (GCF), '4w'.
4w(6 + w) = 0
Ignore the factor 4.
Subproblem 1
Set the factor 'w' equal to zero and attempt to solve:
Simplifying
w = 0
Solving
w = 0
Move all terms containing w to the left, all other terms to the right.
Simplifying
w = 0
Subproblem 2
Set the factor '(6 + w)' equal to zero and attempt to solve:
Simplifying
6 + w = 0
Solving
6 + w = 0
Move all terms containing w to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + w = 0 + -6
Combine like terms: 6 + -6 = 0
0 + w = 0 + -6
w = 0 + -6
Combine like terms: 0 + -6 = -6
w = -6
Simplifying
w = -6
Solution
w = {0, -6}
