Answer:
(a) 0.9412
(b) 0.9996 ≈ 1
Step-by-step explanation:
Denote the events a follows:
= a person passes the security system
= a person is a security hazard
Given:

Then,

(a)
Compute the probability that a person passes the security system using the total probability rule as follows:
The total probability rule states that: 
The value of P (P) is:

Thus, the probability that a person passes the security system is 0.9412.
(b)
Compute the probability that a person who passes through the system is without any security problems as follows:

Thus, the probability that a person who passes through the system is without any security problems is approximately 1.

No she is not correct
Step-by-step explanation:
She is not correct because “value of expressions” mean the result which for this it is 16-13 =3 and she is wrong. please mark me brainly! Hope this helps! :D
40 miles per hour. if you take 60 divided by 1.5(the speed over time) you get 40mph
Answer:A=62AED B=93 C=155
Step-by-step explanation:
You add all of the numbers to split between (2,3,5) you get 10
then you divided 310 by 10 which is 31
then you times 2 by 31=62 (a)
3x31=93 (b)
5x31=155 (c)
