Answer:
a) The probability that exactly 41 of the murders were cleared is 0.0013
b) The probability that between 36 and 38 of the murders, inclusive, were cleared is 0.0809.
c) Yes, it would be unusual
Step-by-step explanation:
Let p=62% considered as the probability of having a commited that is cleared by arres or exceptional means. We assume that choosing each of the 50 commited is independent of each choose. Then, let X be the number of cleared. In this case, X is distributed as a binomial random variable. Recall that, in this case,
for
, with p=0.62
a) We have that
b) We are asked for the following
(The specific calculation is omitted.
c) We will check for the following probability 
Given that the probability of this event is really close to 0, it would be unusual if less than 19 murders are cleared.

So A for thAnks for the free points
Answer:
her distance would be 0 after 8 hours since 8*3 = 24 and just add a zeor behind the 24 from the 30
Step-by-step explanation:
You started out as if it was going to be a probability problem, but it turned out to be a simple binary counting problem.
It really doesn't matter how many of each color are in the bag, or how many marbles there are in the bag all together. I think you're just asking how many ways there are to pull out two white ones and two black ones. That's exactly the same question as "How many 4-bit binary numbers can be written with two 1's and two 0's ?"
It's easy to draw up that list. You start out like this:
0011, 0101, 1001, 0110, 1010, 1100 .
Gosh. I just wanted to start out doing the list, but I think that's all of them.
There are six (6) ways.
WWBB, WBWB, BWWB, WBBW, BWBW, and BBWW .
Hello, please consider the following.
When you have a complex number in the denominator you need to multiply by its conjugate to eliminate the imaginary component.
The conjugate of 4 - 3i is 4 + 3i, right?
So, let's do it!
Thank you.
