A certain type of rocket has a failure rate of 1.5%.
Use the methods developed in this section to determine the probability of fewer than 4 failures in 100 launches.
Now how do you do FEWER questions? Because I tried doing:
100C0 ( .015) ^ 0 ( 1-0.15)^100....+100C3 (.015)^3(0.985)^97= .71
But the answer is .9358, so I guess Im wrong on how to do questions when they say FEWER THAN.
So how do you do them?
Thanks for the help =)
