In this question, we are given z equal to minus 4.
00:05
Now we have to find the area to the left, left of z equal to minus 4.
00:11
So in normal curve, it goes like this.
00:14
This is z equal to minus 4.
00:16
For this area, we have to find it out.
00:18
That is left of z equal to minus 4.
00:22
Hence, the required area is 0 .0003.
00:26
That is the required area.
00:27
The second one is we are given z equal to minus 8.
00:32
So we have to find the area to the left.
00:35
So which means that it is definitely 0 because we are considering only the range as minus 3 to plus 3.
00:44
Third one, z equal to minus 30...
