Hello, so today i'm going to answer your question about achievements and a specific application of the binomial distribution.
00:07
For doing so first, i sketch the binomial distribution here.
00:11
In the initial nominal distribution, you will see that there are three components and the number of trials, x, the specific amount of success that you want to measure a p, the probability of a single success.
00:22
I think the dynamite distribution would be the right formula to use, because in this case you want to measure the specific amount of times that a shipment will arrive from time.
00:31
As you can see, we need to calculate p.
00:33
P would be the probability that the shipment arrived on time.
00:36
That is the complement of the previous end that i tell you.
00:39
The 3 of the 5 shipments did not arrive on time, so 2 out of 5 arrive on time.
00:45
This would be this probability.
00:47
Now for the probability that x is bigger or equal than 7, you can just take each of the cases, so 7, 8, and i added until 9...
