Answer:
0.9999
Step-by-step explanation:
Let X be the random variable that measures the time that a switch will survive.
If X has an exponential distribution with an average life β=44, then the probability that a switch will survive less than n years is given by
So, the probability that a switch fails in the first year is
Now we have 100 of these switches installed in different systems, and let Y be the random variable that measures the the probability that exactly k switches will fail in the first year.
Y can be modeled with a binomial distribution where the probability of “success” (failure of a switch) equals 0.0225 and
where
equals combinations of 100 taken k at a time.
The probability that at most 15 fail during the first year is
Answer:
224 7/10 is a mixed fraction ..so first we convert it into an improper fraction ...
=> for that follow these steps ...
=> 224 X 10 + 7
=> 2247/10
so now to get in decimals ..we divide 2247 by 10..
=> 224.7 ...
so here we got 224 7/10 in its decimal form ...
