Hi, i'm david and i'm hitchie, have you understand your question? now let me pick up your question here.
00:07
In the question here we are going to discuss about the portion distribution.
00:12
Let me remind you that if the x that followed by the possum when the lambda as a mean, and then the probability of x equals k, if it will equal to each the power minus lambda, lambda power k, over k factorial.

In this question here, we're given a probability, the x equal to the number of the accidents per week so the number of the accidents per week and it will follow by the possum with the mean lambda equal to the 3 now in the question a when you find the probability that no accident occur in a week so want you find probability x equal to the zero now to find this probability it will apply the formula when the lambda equal to the 3 then we have the e to the power minus 3, 3 by 0 over 0 factorial.

And if we compute this one, i will have, let me compute for you, for the post -song distribution.
01:32
We will have, this will be the 0, this will be the 3, and we get equal to the 0 -0, 4, 979...
