Question

HELP WITH 2 QUESTIONS PLEASE! WILL MEDAL AND FAN!

Answer 1

I think that the probability is equal to the ratio between the area of region II, namely 8 little squares over the total area, namely 22 little squares , so:
\[probability=\frac{ 8 }{ 22 }=\frac{ 4 }{ 11 }\]

Answer 2

so A

Answer 3

please, note that the above procedure is based on the classic definition of probability, namely:
probability= ratio between favorable cases over possible cases.
Yes I think A.
Please, tell me if my reasoning is clear for you!

Answer 4

assuming each point is equally likely :)

Answer 5

I give you a useful reference:
I.M. Sobol "The Monte Carlo Method", Mir Publishers Moscow, 1984

Answer 6

that's right! @perl

Answer 7

I would like to read that, if thats online

Answer 8

for part b) you are given that you land in Pennsylvania

Answer 9

Answer 12

I got, here it is:

Answer 13

for your second question, we have to calculate this ratio:
\[probability=\frac{ water-area }{ water-area+ Land-area }=\frac{ 1239 }{ 1239+44817 }=0.027\]

Answer 14

Note that, in this second case I have applied the classical definition of probability

Answer 15

Thank You! may you please help me with 1 more?

Answer 16

yes!

Answer 17

please, you have to apply the same reasoning that I used in the two above exercises, namely:
probability=(favorable area)/(total area)
