The weather forecast for the weekend is a 46% chance of rain for Saturday and a 54% chance of rain for Sunday. If we assume that consecutive days are independent events. What is the probability that it rains over the weekend (either Saturday or Sunday)? Please use 3 decimal places.

In fact, weather on consecutive days depends on similar atmospheric conditions and therefore consecutive days are not independent events. With the weather forecast of the previous exercise, the probability that it rains over the weekend (either Saturday or Sunday) is:

A. 0.7516

B. 0.3758

C. 0.2484

D. Because consecutive days are not independent, we cannot compute P(rain both days) with the information given.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
