Suppose that we toss a coin and roll a dice, and we've been given the sample space for the results.
00:08
So first of all, we have 12 possible results here, 12 unique combinations of a dice roll and a coin toss.
00:17
But because the dye and the coin are fair, each of these is equally likely.
00:24
So each outcome has the same probability.
00:26
There are 12 of them, so each is one in 12th.
00:30
So for part a, we want the probability of tails and an even number.
00:38
So all i need to do is make a fraction where i have 12 as the denominator, and the number of outcomes that meet my criteria as the numerator.
00:50
Okay, so out of 12, how many have tails and even? well, i can see there are three.
00:59
Two and tails, four and tails, six entails...
