If a fair six-sided die is rolled three times, what is the chance of getting at least one ace ? note: an ace is the number 1.

1 answer:

4 0

Recall that the probability of multiple events occurring is equal to their individual probabilities. The chance of rolling a one is 1/6, so the chance of that occurring three times is (1/6)^3, which is equal to 1/216.

The correct answer is: Option (A) $\frac{v-z}{w-x}$ 

Explanation:
If both lines are parallel, then their slopes must be equal.

For the line PQ, the slope is:
Slope of PQ = $\frac{v-z}{w-x}$ --- (1)

For the line P'Q', the slope is:
Slope of P'Q' = $\frac{v+b-z-b}{w+a-x-a}$
Slope of P'Q' = $\frac{v-z}{w-x}$ --- (2)

As (1) = (2), hence the lines are parallel and their slope is $\frac{v-z}{w-x}$ (Option A).
