Hello.
00:02
So let's see how we can find this probability.
00:04
So the first one is the probability of negative 1 .41 less than z less than 0 .61.
00:17
This is going to be the same as the probability of z less than 0 .61 minus probability of z than negative 1 .41.
00:30
So using the z table 0 .61 gives the probability of 0 .70.
00:37
907 when z is 1 .41 that's negative 1 .41 your point 0 .07 927 so our probability is going to 5707 minus 0 .7 .927 you're going to have 0 .6498 let's look at the second one.
01:31
That is between 0 .55 and 1 .78.
01:46
So we're going to have the z.
01:49
1 .8 minus probability of z.
02:00
So let's look at the probability from the z table.
02:04
0 .78.
02:10
That's 0 .96, 246.
02:14
0 .9246.
02:19
The word z is 0 .55.
02:24
We have 0 .70884.
02:37
So 0 .96246 minus 0 .784.
02:48
We're going to have 0 .2253.
02:55
62.

Let's look at a c...
