Question

If the weather prediction of a weather station was correct for 125 days out of 200 days, then find the probability of a wrong prediction on a given day.

• A. 0.375
• B. 0.735
• C. 0.537
• D. 0.573

Answer 1

The correct option is A 0.375

Number of days when prediction was not correct = 200 - 125 = 75 days
We know that,
$Probability=\frac{Numberoffavourableoutcomes}{Numberoftotaloutcomes}$

$\Rightarrow Probability=\frac{75}{200}$

$\Rightarrow Probability=\frac{3}{8}$

$\therefore Probability=0.375$
