In this problem, we are given that there is a normal distribution and we have to find the probabilities in the different cases.
00:08
So first we have to get the probability that the z score is less than minus 1 .35.
00:14
And we just use the z table and we find this as 0 .0885.
00:20
And in the next case, we have to find the probability that the z score is greater than 1 .48.
00:25
So that would be one minus probability that the z score is less than 1 .48.
00:30
And using the z table, we find the probability as 0 .9306.
00:36
And after we subtract, we get 0 .0694 as the result.
00:41
And in the next part, we are required to find the probability that the z score is greater than minus 0 .4, but less than 1 .5.
00:50
So this would be the probability that the z score is less than 1 .5 minus probability that the z score is less than minus 0 .4...
