Since the time to failure distribution is
exponential, the distribution is F (n) = 1 – e ^ (-x/48)
The probability of failure between months 60
and 72 is the same as the probability that the battery will fail in 12 months,
since the exponential distribution is memoryless F (12) = 0.221

Answer:
4
Step-by-step explanation:
If she got a 90% on her test, and the test was 40 questions long, we need to do a bit of division and multiplication.
We have to divide 40 by 100, as percentages are out of 100.
So now we have 0.4.
Now we multiply this by 90.
36. She got 36 answers correct out of 40, which means she got four wrong.
