Let's play a game of Russian roulette. You are tied to your chair. Here's a gun, a revolver. Here's the barrel of the gun, six c

4vir4ik [10]

Answer:

Don't spin the barrel.

Step-by-step explanation:

Each time you spin the barrel, the probability A of finding a bullet, having two bullets in six chambers is:

$P(A)=\frac{2}{6}=\frac{1}{3}=0.33$

For you to get shot in the second try but not the first, the barrel spin would have to stop precisely at one specific chamber: the one right before the bullets, so that probability would be:

$P(B)=\frac{1}{6}=0.17$

which means that this event is half as likely as finding a bullet every time the barrel is spun. Your chances are better if you pull the trigger for the second time without spinning the barrel.

The equation C=2(3.14)r is the formula that relates the circumference of a circle to the radius. This gives us the ability to ca

Hello from MrBillDoesMath!

Answer:

r = C/6.28

Discussion:

Note that C = 2 * Pi * r is the exact formula. As Pi is approximately 3.14, the given formula, C = 2 (3.14) r, is an approximation. Solving it for r:

C = 2(3.14) r => as 2 * 3.14 = 6.28

C = 6.28 r => divide both sides by 6.28

r ( 6.28/6.28) = C/6.28 => as 6.28/6.28 = 1

r = C/6.28

Thank you,
