Using the arrangements formula, it is found that they find 46200 ways.
<h3>What is the arrangements formula?</h3>
The number of arrangements of n elements is given by:

If they repeat in
ways, the number of arrangements is given by:

In this problem, 11 elements are arranged with repetitions of 4, 3 and 3, hence:

They find 46200 ways.

For this question you can say:
log(x-2) - log(x+1) = -1
and you should know that log(x-2) minus log(x+1) is equal to:
log((x-2)/(x+1))
so now you have:
log((x-2)/(x+1)) = -1
now you can say:
(x-2)/(x+1) = 10^ -1 or (x-2)/(x+1) = 1/10
now you can say:
10(x-2) = x+1
10x -20 = x +1
10x - x = 20+1
9x = 21
x = 21/9
x = 7/3 :)))
I hope this is helpful
have a nice day
the answer to the problem is 1/4
Answer:
Solution: given that
n = 38
p = 2/5 = 0.4 q = 1-p = 1-0.4 = 0.6
standard deviation = sqrt(n*p*q)
sqrt(38*0.4*0.6) = 3.0199
