Today i'm going to be walking you through how to solve this problem.
00:04
This problem asks us the probability that exactly 12 of 15 in d race drivers were survived a crash, given that 95 % and then survive a crash.
00:14
Okay, so we're looking for 12, whoopsie, we're looking for 12 out of 15 that survived a crash.
00:22
And the probability of dying in a crash, let's put that as probability of d is equal to 95, i'm sorry, the probability of living in the crash, probability of l, is equal to 0 .95 or 95%.
00:39
And, okay, so what we can do here is we can use a simple tool in statistics called binomial pdf.
00:48
This function is available in every, pretty much every graph and calculator.
00:53
And what we do here is, let me clear these.
00:56
This is for my last question.
00:59
What we do here is we fill the blanks.
01:01
This first blank asks us the probability of success in a single trial.
01:06
Now this inner scenario would be the probability of the biker or driver living in a crash, which is 0 .95 or 95 %...
