This problem, it is said that you roll a six -sided die, and we need to find the probability of each of the given scenarios.
00:07
So in the first one, we need to determine the probability of rolling a four or a number greater than three.
00:13
So the probability, that will be the number of favorable outcomes divided by the total number of outcomes.
00:18
Now, when we roll a die, the possible outcomes are 1, 2, 3, 4, 5, and 6.
00:24
So that means that the total number of outcomes is 6.
00:27
And consider the favorable outcomes.
00:29
So the favorable outcomes are four and the number is greater than three.
00:33
So we have four, five, and six.
00:37
So there are three favorable outcomes.
00:39
There are three ways you can roll a four or a number greater than three.
00:43
So we have three divided by six.
00:46
That is equal to half if we reduce the fraction by three, and that's equal to 0 .5.
00:51
So that's our required probability, 0 .5 .0 because we have been asked around three decimal places.
01:00
Next, we need to determine the probability of rolling a number less than five or an even number...
