Answer: a)
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 occurs together = .
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)
Hence, the probability that when a theft occurs, all four systems will detect it is .
Hence, the correct answer is a) .
Answer:
(52/52)(48/51)(44/20)(40/59)(36/48)
Step-by-step explanation:
For the first card, what is the chance of getting a unique value? Well, you don't have any yet so it's 100% or 52/52.
Now for the second draw, what is the probability of not getting a repeat? Well, 52 cards total but there are four copies of every value, one for each suit. The deck now has 51 cards and 48 are not copies, so that's 48/51.
Similarly for the third draw there are now 50 cards total and 44 are not going to be repeats if the last two were not.
You can keep going like this and you get (52/52)(48/51)(44/20)(40/59)(36/48). Hopefully this made sense.

Answer:
3 1/5 minutes per meter
Step-by-step explanation:
To find the rate in minutes per meter, divide the number of minutes by the number of meters:
(2.4 min)/(0.75 m) = 3.2 min/m = 3 1/5 minutes per meter
