0.17 becomes 0.2 square miles.
This is because the tenth number is the number right after the decimal point.
If the number in the hundredths column (the one after the tenths) is greater than 5, the tenth will be rounded one number up, so 0.17 becomes 0.2.
If the number in the hundredths column is less than 5, e.g. 0.13, the number would be rounded to 0.1.
Answer:
[r/(w + r)]^4
Step-by-step explanation:
The numbers of the different balls are not given, but here is the solution.
Let w = number of white balls.
Let r = number of red balls.
The total number of balls is w + r.
All drawings have the same probability since there is replacement.
Each drawing has the following probability of drawing a red ball:
p(red) = r/(w + r)
Since there are 4 drawings, and they are all independent events, the overall probability is the product of the individual probabilities.
p(4 red balls in 4 drawings) = [r/(w + r)]^4
To find an actual number, replace w and r with the correct numbers and evaluate the expression.
