The odds of 1 coin landing tails is 1/2, for 2 coins it would be 1/4, 3 would be 1/8, 4 would be 1/16, etc.
the way you find this is by doing 1/2^n where n is the number of coins you have. if you plug in 20, you get 1/1,048,576
Tangent = Opposite÷ Adjacent
![\tan(angle \: q) = \frac{0pposite}{adjacent} \\ = \frac{6}{3} \\ = 2](https://tex.z-dn.net/?f=%20%5Ctan%28angle%20%5C%3A%20q%29%20%20%3D%20%20%5Cfrac%7B0pposite%7D%7Badjacent%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B6%7D%7B3%7D%20%20%5C%5C%20%20%3D%20%202)
So the answer is D) 2
You have to add 23 and 45 will get 68 then divide 68 by 4 and that is your answer
2+3=5 total people. So we multiply the total amount of people by the 3 lives they each have which would be 15. I hope this helps you :)
