Since there are 128 fluid ounces in a gallon and a raindrop is 1/90, you have to multiply 128 by 90. Since it takes 90 raindrops to get to a whoke fl oz, and you need 128, you hae to multiply:
128×90=11,520
It takes 11,520 raindrops to fill the bucket.
Option B:
Solution:
Given expression:
To find the value of x:
Convert mixed fraction into improper fraction.
Divide by 3 on both sides of the equation, we get
Taking square root on both side of the equation.
Convert improper fraction into mixed fraction.
Hence option B is the correct answer.
Answer:
First, we have two marbles, and i guess that each one has the same probability of being picked at random (actually they have different densities, so one may have a larger probability than the other).
The possible outcomes are:
S G
S S
G S
G G
Now, suppose that we want to find the probability of the S G outcome.
In the first selection, we want to pick the silver marble, with a probability of ps,
In the second selection, we want to pick the gold marble, with a probability pg
As the events are independent, the joint probability will be equal to the product of the probabilities for each selection:
P = ps*pg
Now, if both marbles have the same probability of being picked, then:
ps = 0.5
pg = 0.5
P = 0.5*0.5 = 0.25
And this will be the same for each outcome.
