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?

• A. $0.9$
• B. $0.8$
• C. $0.7$
• D. $0.6$

Answer 1

Answer: (C)

$0.7$

Total no. of days for which record of weather is given $=250$
No. of days for which forecasts were correct $=175$
$\therefore$ favorable days $=175$
$\therefore$ probability $=\frac{175}{250}=0.7$
