Question

The
Record of a weather
station shows that
past
300 days, its weather
forecast were correct

250 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

Answer:

Step-by-step explanation:

i) Probability on a given day that it was correct = 250/300  = 5/6

ii) Probability on a given day that it was not correct = 50/300 = 1/6

[not correct = total- correct = 300-250 = 50

Answer 2

Answer:

(1/6)

Step-by-step explanation:

Total number of days for which weather forecast was recorded = 300

Total number of possible outcomes = 300

Number of days for which forecast was correct = 250

Number of days for which forecast was incorrect = 300−250=50

Hence the number of Number of favourable outcomes for not correct= 105

The probability that on a given day it was not correct = Number of favourable ooutcome/

Total number of possible outcomes

= (50/300) = (1/6)
