If the mine winch drum diameter is 6 m, calculate how far the cage will drop for each single rotation of the drum.use formular c

frozen [14]

The cage will drop 18.84m for each single rotation of the drum.

It is given that the diameter of the mine winch, d= 6 m.

We can calculate that how far the cage will drop for each single rotation of the drum by using the formula of the circumference.

Circumference, c = 2πr

where,

r = d/2 (radius of the mine winch)

r = 6/2

⇒ r = 3m

Circumference, c = 2πr

⇒ c = 2π×(3)

⇒ c = 6π

⇒ c = 18.84m

Hence, the cage will drop 18.84m for each single rotation of the drum.

An arcade booth at a county fair has a person pick a coin from two possible coins available and then toss it. If the coin chosen

Answer:

Step-by-step explanation:

<u>Conditional Probability</u>

Suppose two events A and B are not independent, i.e. they can occur simultaneously. It means there is a space where the intersection of A and B is not empty:

$P(A\cap B) \neq 0$

If we already know event B has occurred, we can compute the probability that event A has also occurred with the conditional probability formula

$\displaystyle P(A|B)=\frac{P(A\cap B)}{P(B)}$

Now analyze the situation presented in the question. Let's call F to the fair coin with 50%-50% probability to get heads-tails, and U to the unfair coin with 32%-68% to get heads-tails respectively.

Since the probability to pick either coin is one half each, we have

$P(U)=P(F)=50\%=0.5$
