There's no way to answer this with a single probability. All that can be done is to review weather reports from one year ago, two years ago, three years ago (and so on) and base an estimate (of having a sunny day) on this historical data.

Assuming that your choices are sunny and not sunny. There would be a 50% chance that a year from today will be sunny.

Therefore the answer would be 1/2 or 50%.

Ray Of Light [21]

Answer:

c. 60.9%

Step-by-step explanation:

Given:

The probability P that a person responds to an advertisement can be modeled by the function:

$P=1-e^{-0.047t}$

where $t$ represents number of days since the advertisement first appeared.

To find the probability that a person has responded after 20 days.

Solution:

In order to find the probability that a person has responded after 20 days, we will plugin $t=20$ in the formula given.

We have:

$P(t)=1-e^{-0.047t}$

Plugging in $t=20$

$P(20)=1-e^{-0.047(20)}$

$P=1-e^{-0.94}$

$P=1-e^{-0.047t}$

$P=1-0.3906$

$P=0.6094$

Thus, probability $P$ after 20 days = 0.6094

The probability in percentage can be given = $0.6094\times 100$ = 60.9%
