Answer:
B) Observing how probability works with real items
Step-by-step explanation:
Just took the quiz :)
Assuming that all the grapes have the same probability of being randomly picked:
<h3>
How to find the probabilities?</h3>
We know that there are 8 green grapes and 15 red grapes on the bowl, so there is a total of 23 grapes.
a) Here we need to find the probability that both grapes are green. Remember that the probability of getting a green grape is equal to the quotient between the number of green grapes and the total number of grapes, this is:
P = 8/23
But then he must take another, because he already took one, the number of green grapes is 7, and the total number of grapes is 22, so for the second grape the probability is:
P' = 7/22.
The joint probability is the product of the two individual probabilities:
prob = (8/23)*(7/22) = 0.11
b) For the first green grape we know that the probability is:
P = 8/23
Then he must get a red grape. There are 15 red grapes and 22 grapes in total, so the probability is:
P' = 15/22
Then the joint probability is:
prob = (8/23)*(15/22) = 0.24

Answer:
that's as simple as it gets
Step-by-step explanation:
"Simplify" usually means "combine like terms, rationalize the denominator, reduce radicals to the greatest extent, cancel common factors from fractions, eliminate parentheses," and the like.
When a function of a single variable is multiplied by a single constant, there is no simplification that can be done.

_____
If your ∅ is supposed to be zero, then cos(0) = 1 and it simplifies to 18.
Answer:
Step-by-step explanation:
12x³ = 2²·3·x³
The greatest common factor of 12x³ and 3x² is 3x².
12x³ - 3x² = (4x - 1)3x²
