For safety reasons, four different alarm systems were installed in the vault containing the safety deposit boxes at a Beverly Hi
larisa [96]

Answer: a) (0.99)^4

Step-by-step explanation:

Given : For safety reasons, four different alarm systems were installed in the vault containing the safety deposit boxes at a Beverly Hills bank.

Each of the four systems detects theft with a probability of .99 independently of the others .

Probability for independent events (E_1 , E_2 , E_3 , ....., E_n) occurs together =  P(E_1)\times P(E_2)\times P(E_3)\ .....\times P(E_n).

Then, the probability that when a theft occurs, all four systems will detect it

= (0.99) x (0.99) x (0.99) x (0.99)

= (0.99)^4

Hence, the probability that when a theft occurs, all four systems will detect it is (0.99)^4 .

Hence, the correct answer is a) (0.99)^4 .
