Answer:
they are different because of the mode sign on the second 's',
which if you are wondering what it stands for,
it represents only the magnitude of the value needed, not its sign,
let the assumed value of s be -5,
for example iin the first case, s < 3
hence s = -5, and it is true for s < 3
OR
if we take the second case, lsl < 3
that would be s = 5 [ not -5], which would not be true for lsl < 3
i hope u understood it,
if any more questions...please ask :)

Step-by-step explanation:
Answer:
a)P=0.42
b) 
Step-by-step explanation:
We have a binomial distribution, since the result of each experiment admits only two categories (success and failure) and the value of both possibilities is constant in all experiments. The probability of getting k successes in n trials is given by:

a) we have k=2, n=10 and p=0.01:

b) We have,
, Here P is the probability that at least one particle will penetrate the shield, this probabity has to be equal or greater than 0.95. Therefore, this will be equal to subtract from the total probability, the probability that the particles do not penetrate raised to the total number of particles.
