Answer:
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z-----> the scale factor
x----> the volume of the planet's moon
y---> the volume of the planet
so
In this problem we have
elevated to the cube
Find the percent
Round to the nearest whole number
Given:
Total number of book = 22
Number of white books = 6
Number of Purple books = 9
Number of green books = 7
To find:
The probability that Warren takes out a green book in both draws (with replacement).
Solution:
We know that,
After replacement, the probability of event remains the same and the independent.
The probability that Warren takes out a green book in both draws is:
Therefore, the correct option is (a).
