In this problem, we are given that there are two dice and both of them are rolled together.
00:09
And first we have to compute the probability of getting sum which is equal to 5.
00:14
So we will consider e here as the event of getting sum of 5 when two dice are rolled.
00:20
And the outcomes which will be favorable to this event e, it will be one on one dice, four on the other, two on one, three on the other.
00:28
Similarly, we will have three, two and four, one.
00:30
So if we count, we see that the number of outcomes which is favorable to this event is four and the total number of outcomes, well that will be six times six, which is equal to 36.
00:40
Because we know that when we roll a dice once, we have six possible outcomes, which are the numbers through one to six.
00:48
And to get the probability, we will simply use this formula, according to which we see that the probability of the event is obtained when we divide the number of outcomes that's favorable with the total number of outcomes.
00:59
And doing that, we get one by nine as the result.
01:03
And in the next part, we have to get the probability of getting a sum which is eight or six.
01:11
So we will consider f here as the event of getting sum of eight or six...
