Question

The record of a weather station shows that out of the past $250$ consecutive days, its weather forecasts were correct $175$ times.

What is the probability that on a given day it was correct?

Answer 1

Total number of days for which the record is available$=250$

Number of days when forecast was correct$=175$

$P\left(theforecastwascorrectonagivenday\right)=\frac{Numberofdayswhenforecastwascorrect}{Totalnumberofdaysforwhichtherecordisavailable}$

$=\frac{175}{250}=0.7$
