Answer: it’s the third one
Step-by-step explanation:
Answer:
There are 6*5*4 = 120 possible 3-digit numbers, of which 60 must be even and 60 must be odd, since there are 3 even possible ending digits and 3 odd possible ending digits.
Step-by-step explanation:
Answer:
- 24
Step-by-step explanation:
We have to get the value of the following sum as given.
This can be written in language as the summation of (12 -4i) where value of i ranges from 3 to 6.
= [12 - 4(3)] + [12 - 4(4)] + [12 - 4(5)] + [12 - 4(6)]
= 0 + [- 4] + [- 8] + [- 12]
= - 24 (Answer)
Answer:
12.76% probability that there is exactly 1 reported crime on any given day.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
Statistics from the Riverside Police Department show that in the last 12 years there were 648 reported crimes in the city.
Each year has 365 days. We want the mean for a day. So

Find the probability that there is exactly 1 reported crime on any given day.
This is P(X = 1).


12.76% probability that there is exactly 1 reported crime on any given day.
Answer:
