This is a statistics problem on permutation and combination. To differentiate this, permutation involves on the arrangement in which order doesn't matter. For combination, order matters.
For example, if you arrange A, B and C, for permutation it could be AB, BA, CA, AC, BC and CB. But for combination, it would just be AB, AC and BC.
So, in this problem where he is asked to arrange 8 jars in which order doesn't matter. It is permutation. You can solve this just by calculator. The formula would be nPr, where n is the total number of items while r is the number of items to be sorted. Thus,
nPr = 10P8 = 1, 814,400
Thus, the answer is B.
Answer:
X=20; pqr = 130°
Step-by-step explanation:
They key here is to notice that the instructions say that qs bisects pqr, meaning that it evenly cuts it into 2 pieces. So, to find x, you just solve for x in the equation 3x+5=2x+25. Then, you plug it back into either side of the equation, at which point, you should get 65. Since it is half of pqr, just double it to get your final answer of 130°

Answer:
0.05991, 0.003589
Step-by-step explanation:
Given that a study of the adequacy of New York City’s snow-fighting capability estimated that the number of snowstorms in a season was approximately (remember the continuity approximation) normally distributed with a mean of 6.5 and a standard deviation of 2.25.
X- number of snowstorms is N(6.5,2.25)

Assuming independence we can say Y the no of snowstorms >=2 is
Binomial with n =3, and p = 0.05991
the probability that New York City will have more than 10 snowstorms in at least two of the next three seasons
=
