i dont think you need a poisson distribution here.
if two trucks pass before the next one fails, then you must have the next two trucks passing. These are independant (i assume) with probability 75% each.
can you finish from there?
Hi
Can someone help me on how to answer the following question:
In testing a certain kind of truck tyre over rugged terrain, it is found that 25% of trucks suffer tyre blowout.
What is the probability that at least two trucks will complete the course without tyre blowout before the next truck suffers from tyre blowout?
I think this is using Poisson distribution but not sure.
Such as Pr( without blowout > 2) + Pr( with blowout > 2)
P.S
