Question

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

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

      (ii) What is the probability that it was not correct on a given day?

Answer 1

(I) 175/250=7/10
(ii)250-175=75
75/250=3/10
hope it'll help

Answer 2

Hey!!!!


1. Total Outcomes (n) = 250

Favourable Outcomes (m) = 175

P(getting correct weather forecast) = m/n

=> 175/250
=> 7/10
=> 0.7

2. Favorable Outcomes (m) = 250 - 175
= 75

Thus P(getting incorrect weather forecast) = m/n

=> 75/250
=> 3/10
=> 0.3

Hope this helps
