Hi, i'm david and i'm here to have you answer your question.
00:04
Now let me bring up your question here.
00:07
In this question we discuss about the partial distribution approximation to the binomial.
00:14
Let me remind you that if we have the x followed by the bin and the b, and if we have two conditions, first and is large and b is small, and then we can approximate the x by the possum with the rate lambda equal to nb.
00:38
Also notice that proper medium the possum equal to k, it will equal to e bha minus lambda lambda power k, over k factorial.
00:48
Now in this question we're given the proper premium the flaw equal to j -1 -002 and we have n it will equal to 50 shut and in each shot we have five, six buttons.
01:03
So n equal to the 50 times six, so equal to 300.
01:08
From here we see if we can x equal to the number of the floor in 300 buttons, in 300 buttons.
01:25
And then we will see that x will follow by the binomial with the n equal to the 300 and the p equal to z -pon -zero -two.
01:39
And we can use find some approximation to the normal, where n lambda equal to 2 and times b will be 300 times with the 0 .0.
01:55
Then we get equal to 0 .3...
