Answer: a) 0.2222, b) 0.3292, c) 0.1111
Step-by-step explanation:
Since we have given that
Let the probability of getting head be p.
Since, its head is twice as likely to occur as its tail.

a)If the coin is flipped 3 times, what is the probability of getting exactly 1 head?
So, here, n = 3


Now,

b)If the coin is flipped 5 times, what is the probability of getting exactly 2 tails?
2 tails means 3 heads.
So, it becomes,

c)If the coin is flipped 4 times, what is the probability of getting at least 3 tails?

Hence, a) 0.2222, b) 0.3292, c) 0.1111
The distance between the two points is -12
30% is .3 so 20 times .3 is 6 extra miles so 30 plus 6 is 36 miles
So you want to know how many times

fits inside

, if so, here's the answer:
First we see that

is equal to <span>4,000,000, and</span>

is equal to 10,000.
Then we divide

, and we get 400, so.
The answer is 400.
Hope this helped! c:
53.8516 if you are use the Pythagorean theory. You create a triangle making the longest line the C.
