Answer:
0.980
Step-by-step explanation:
The probability that the noise level of a wide-band amplifier will exceed 2 dB is 0.05
So, probability of success = 0.05
Probability of failure = 1-0.05=0.95
There are 12 amplifiers
We are supposed to find the probability that at most two will exceed 2dB.
We will use binomial distribution
Formula :
p = 0.05
q = 0.95
n = 12
We are supposed to find the probability that at most two will exceed 2dB.
So,
Hence the probability that at most two will exceed 2dB is 0.980
