Answer:
the answer will be 7.5 feet
Step-by-step explanation:
Let X be the number of lightning strikes in a year at the top of particular mountain.
X follows Poisson distribution with mean μ = 3.8
We have to find here the probability that in randomly selected year the number of lightning strikes is 0
The Poisson probability is given by,
P(X=k) =
Here we have X=0, mean =3.8
Hence probability that X=0 is given by
P(X=0) =
P(X=0) =
P(X=0) = 0.0224
The probability that in a randomly selected year, the number of lightning strikes is 0 is 0.0224
Answer:
2/15
Step-by-step explanation:
There is a 4/10 probability that she chooses blue the first time, but the second time it is a 3/9 chance because she didn't put the marble back so there are 9 marbles in total, 3 blue ones.
4/10 x 3/9 = 2/5 x 1/3 = 2/15
I hope this helps :)
Edit: Messed up the multiplication, whoops!
Answer:
2.4
Step-by-step explanation:
24/10=2.4
Answer:
11. Eagles to Whales
12. 23:50
13. 27:23
14. 3:5
Step-by-step explanation:
11. Eagles to whales since there are 4 eagles and 2 whales
12. There are a total of 100 senators, so the ratio is 46:100, divide by 2 to get lowest terms
13. #'s are given to you 54:46, just simplify by dividing
14. 21:35, simplify by dividing common terms, which in this case is 7
