Hello, students, we are going to write here probability is equal to 0 .3 for particular smartphone owner, let x is equal to 1 if they have app x is equal to 0 otherwise.
00:11
N value is 40 owners.
00:13
So if i write here for this, in the first case, we are going to write here for this.
00:19
P value as 0 .3, we are going to write here be the proportion of proportion of, proportion of if i write here for this smartphone owners we are going to write here for this this must be written as who have who have given we are going to write here for this who has who has given we are going to write here for this app who has given we are going to write here for this from the given data from so this must be written as we are going to write here for this so we are going to write this must be written as from the given data from the given data given data this must be written as x is equal to one when the smartphone have a app a smartphone have a have a app we are going to write here for this this must be written as x is equal to zero or when x is equal to zero when the smartphone, so let's erase this to make it more clear, smartphone, if i write here for this, this must be written as don't have a app, do not have a app.
02:18
We are going to write here for this, this must be written as.
02:22
So finally in the a part we can write here probability of x value is equal to 1 which is 0 .3.
02:31
We are going to write here for this.
02:34
This must be 0 .3.
02:36
And if i write here what would be probability of x is equal to 0? this is 1 minus 0 .3 which is 0 .7.
02:45
So probability of x values equal to 0 is 0 .7.
02:49
And if i write here, we are going to write here for this...
