Calculate distance FC
FC is calculated as:
Where
Considering 
, we have:
--- Pythagoras theorem
Where
and
So:
Take square roots of both sides
So:

So;
Recall that:
it's D becuase when you round all of them 124.2 is the only one thats different.
124.5 Rounded is, 125
125.3 Rounded is 125
124.9 Rounded is 125
124.2 Rounded is 124
Hope this helps. (i'm doing the same test lol)
Answer:
Here, we have:
P(5 days snow in this 8 days) = 8C5 x (0.85)^5 x (1 - 0.85)^3 = 0.084
P(6 days snow in this 8 days) = 8C6 x (0.85)^6 x (1 - 0.85)^2 = 0.238
P(7 days snow in this 8 days) = 8C7 x (0.85)^7 x (1 - 0.85)^1 = 0.385
P(8 days snow in this 8 days) = 8C8 x (0.85)^8 x (1 - 0.85)^0 = 0.272
Add up those above, then the probability that it will snow AT LEAST five of those days in February:
P = 0.084+ 0.238 + 0. 385 + 0.272 = 0.979
Hope this helps!
