Suppose an airport metal detector catches a person with metal 99% of the time. That is, it misses detecting a person with metal

frozen [14]

Answer:

The probability of missing the first metal-carrying person is P(x≤50)=0.395

Step-by-step explanation:

p=0.01

P(x)= $\frac{n!}{x!(n-x)!} p^x(1-p)^{n-x}$

We look for the probability when all metal carring people is detected so x=0

P(x≤50)=1-P(x=0)= $1 - 0.99^{50}$ =0.395
