Question

When rolling a six-sided number cube and flipping a

coin, what is the probability of landing on tails and a
multiple of 3?

Answer 1

There is a one in six chance of rolling a six and a one in two chance of getting tails. We can write this in mathematical notation as:

Let the result of the dice role = d

Let the result of the coin toss = c

prob (d=6)∩ prob (c= tails )

=16∗12

=112

The ∩ symbol means the intersection of two events. When we want the probability of event x AND event y occurring, we multiply their probabilities. This is called the intersection of x and y.
