Hi, i'm david and i'm here to help you answer the question.
00:03
Now in the question here we are going to discuss about the portion distribution.
00:08
Now let me pick up your question here.
00:12
Here if we have the x that follows by the possum would the mean equal to the lambda and then the probability of the x equal to the key, it will equal to the e to the power minus lambda, lambda power k our k factorial.
00:34
In the question here we have the x, it will equal to the number of the customers arrive.
00:40
So x equal to the number of customers per two minutes.
00:56
And then x will follow by the possum with the lambda equal to the two.
01:05
And now this one i will call it as per one minute first.
01:10
And then we will have add the rate only 2 per minute so lambda equal to the 2 in this case and in the question a want to find the probability that the next customer will arrive within the 1 minute so it means then want to find the probability that the x will be quite equal to the 1 and then we will have this one would be easier if you consider the common 1 minus the probability of x it will be equal to the 0 and and and then to find this probability if we just use this formula, and then we have one will minus the e to the power of the minus 2, 2 by 0 of 0 factorial.
01:56
And if we compute this one, we have e to the power minus 2, and then 1 minus the answer, get equal to the 186, 47...
