Suppose that the probability that any particle emitted by a radioactive material will penetrate a certain shield is 0.01. if 10 particles are emitted, what is the probability that:
a) exactly 2 of the particles will penetrate the shield?
b) how many particles must be emitted in order for the probability to be at least 0.95 that at least one particle will penetrate the shield?
Answers: 1
, 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.
