Question

a certain hurricane database extends back to 1851, recording among other data the number of major hurricanes (measuring at least a category 3) striking a certain provides a probability distribution for the number of major hurricanes, y, for a randomly selected year between 1851 and 2012. complete parts (a) through (f) below.

yp(y = y)yp(y = y)
10.28160.027
20.26470.008
30.07880.082
40.037

a. {y≥1}
b. use random - variable notation to represent the event that the year had exactly eight major hurricanes. select the correct choice below and fill in the answer box within you
a. {y = 8}
b. p( )
c. use random - variable notation to represent the event that the year had between 2 and 4 major hurricanes, inclusive. select the correct choice below and fill in the answer box
a. {2≤y≤4}
b. p( )
d. use the special addition rule and the probability distribution to determine the probability that the year had at least one major hurricane
the probability is 0.818
(type an integer or decimal rounded to three decimal places as needed.)
e. use the special addition rule and the probability distribution to determine the probability that the year had exactly eight major hurricanes
the probability is
(type an integer or decimal rounded to three decimal places as needed.)

Explanation:

Step1: Identify probability from table

We are looking for $P(Y = 8)$. From the given probability - distribution table, when $y = 8$, $P(Y=y)=0.082$.

Answer:

$0.082$
