In this problem, it is said that a sample space s yields 10 equally likely events, pr, st, u, v, w, x, y, and z, and we need to determine some probabilities.
00:10
First of all, we need to find the probability of t.
00:13
Now, this will be the number of favorable outcomes divided by the total number of outcomes.
00:18
Now, first of all, know that the total number of outcomes will be the total number of equally likely events in the sample space, and it is said that there are 10 equally likely events, so we have 10.
00:28
And the number of favorable outcomes will be 1 because the only favorable outcome in this case is t.
00:34
So we have 1 by 10 that is equal to 0 .10, and so this is our required probability 0 .10.
00:42
Next, we have been asked to determine the probability of our complement.
00:47
Now, using the complement rule of probability, this is equal to 1 minus p of r.
00:52
Now, what is p of r? that's the number of favorable outcomes divided by the total number of outcomes...
