If the probability of a hurricane hitting the gulf coast in any given year is 1/5, what is the probability of the gulf coast getting hit by a hurricane in 3 consecutive years?
a
1/125
b
3/5
c
3/125
d
1/25

A.

Step-by-step explanation:

Given:

Probability of a hurricane hitting the gulf coast in a year is

Let E be the event for the hurricane hitting the gulf coast in a year.

So,

Therefore, probability of hitting the gulf coast for 3 consecutive years will be the product of the probabilities for each  year and is given as:

The probability of the gulf coast getting hit by a hurricane in 3 consecutive years is .

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
