The correct answer is:
$1-\left(\frac{3}{4}\right)^{7}$
The probability of rain in one day
$=\frac{25}{100}=\frac{1}{4}$
Probability of getting at least one rainy day within a period of 7 days
$=1-\left[1-\frac{1}{4}\right]^{7}=1-\left[\frac{3}{4}\right]^{7}$
$=\frac{25}{100}=\frac{1}{4}$
Probability of getting at least one rainy day within a period of 7 days
$=1-\left[1-\frac{1}{4}\right]^{7}=1-\left[\frac{3}{4}\right]^{7}$
