Answer:
umm im not sure if its correct but do 2 ( the colors ) times how many times it is spun. so there are 6 .
Step-by-step explanation:
Answer:
The probability is
Step-by-step explanation:
We can divide the amount of favourable cases by the total amount of cases.
The total amount of cases is the total amount of ways to put 8 rooks on a chessboard. Since a chessboard has 64 squares, this number is the combinatorial number of 64 with 8,
For a favourable case, you need one rook on each column, and for each column the correspondent rook should be in a diferent row than the rest of the rooks. A favourable case can be represented by a bijective function with A = {1,2,3,4,5,6,7,8}. f(i) = j represents that the rook located in the column i is located in the row j.
Thus, the total of favourable cases is equal to the total amount of bijective functions between a set of 8 elements. This amount is 8!, because we have 8 possibilities for the first column, 7 for the second one, 6 on the third one, and so on.
We can conclude that the probability for 8 rooks not being able to capture themselves is
Answer:
The first one.
Step-by-step explanation:
To find the volume of the figure, you need to remember the formula V=LWH (Volume= Length times width times height). The first one accurately represents the formula, therefor the first one is the correct answer.
Answer:
Area = PI * radius ^ 2
Area = PI * 60^2
Area = PI * 3,600
Area = 11,309.73 square miles
