The chance of rain on a randomly selected day in western oregon between june 21st and september 21st is 30% each day. what is the probability it rains at least 2 out of any randomly selected 5 days during the given time of year? (round your answer to the nearest hundredth)

0.47 is the probability it rains at least 2 out of any randomly selected 5 days during the given time of year

Step-by-step explanation:

We are given the following information:

We treat training as a success.

P(Rain) = 30% = 0.30

Then the chances of rain on each day follows a binomial distribution, where

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 5

We have to evaluate:

0.47 is the probability it rains at least 2 out of any randomly selected 5 days during the given time of year

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!
