There is about 87658.1. there are 8765.81 in one year so multiply by ten to get 87658.1.
I’m hoping this helps (but hopefully now you can give the brainliest to the person above)
I’m not very familiar with the square roots method but I believe you try and isolate the term that is squared.
Because the actual dimensions of the board and the target are missing, let us supply the missing values.
Let:
radius of board = 6 inches
radius of target = 2 inches
Area of board = pi * r^2 = pi*6^2 = 36pi
Area of target = pi * r^2 = pi*2^2 = 4pi
Probability of hitting the target = 4pi / 36pi = 1/9
Therefore, there is a 1/9 chance of hitting the target on the board.
12C3 means nCr
You have 12 items of which you want to choose 3 and the order in which you choose them does not matter.
n! 12! 12! 479001600
---------- = -------- = ------- = ----------------- = 220
(r!(n-r)! 3!(12-3)! 3!(9!) 21177280
