Answer:
The probability of the spinner landing on A is 0.1111.
Step-by-step explanation:
The possible outcomes of a board game is that it can lead on any three of the regions, A, B and C.
The probability of all the outcomes of an event sums up to be 1.
![P(E) = P(E_{1})+P(E_{2})+...+P(E_{n})=1](https://tex.z-dn.net/?f=P%28E%29%20%3D%20P%28E_%7B1%7D%29%2BP%28E_%7B2%7D%29%2B...%2BP%28E_%7Bn%7D%29%3D1)
According to the provided information:
P (B) = 3 P (A)
P (C) = 5 P (A)
Compute the probability of the spinner landing on A as follows:
![P(A)+P(B)+P(C)=1\\P(A)+3P(A)+5P(A)=1\\9P(A)=1\\P(A)=\frac{1}{9}\\=0.111111\\\approx0.1111](https://tex.z-dn.net/?f=P%28A%29%2BP%28B%29%2BP%28C%29%3D1%5C%5CP%28A%29%2B3P%28A%29%2B5P%28A%29%3D1%5C%5C9P%28A%29%3D1%5C%5CP%28A%29%3D%5Cfrac%7B1%7D%7B9%7D%5C%5C%3D0.111111%5C%5C%5Capprox0.1111)
Thus, the probability of the spinner landing on A is 0.1111.
Answer:
13
Step-by-step explanation:
The formula for cirmference is
C= π2 * r
we're using 3.14 as pi and r = radius.
the radius is always half of the diameter.
So in this case since the diamter is 4, the radius is 2. let's substitute these numbers.
C= 3.14 *2*2 and there your answer is 12.56 which rounded to the nearest tenth is 13.
Hope this helps :)
