Question

what will be the probilty of raining, if the probiltt of raining is0.73​

Answer 1

Answer:

The answer is

P<1−0.73=0.27  

In Theory of Probability, when two independent events happen, their probabilities may be summed to obtain the total one; in our problem we have two events which are independent:  E1= “Tomorrow it will rain” and  E2= “Tomorrow it will be sunny”.

We know that certainty has probability 1, so if we sum probabilities of events  E1 “Tomorrow it will rain” and  E11 “Tomorrow it won't rain”, we have

P(E1)=0.73  

P(E11)=1−0.73=0.27  

Now, when it's sunny, it means that it doesn't rain, so event  E2 is included in event  E11 and its probability must be less than this.

Answer 2

The answer is

P<1−0.73=0.27P<1−0.73=0.27

In Theory of Probability, when two independent events happen, their probabilities may be summed to obtain the total one; in our problem we have two events which are independent: E1=E1=“Tomorrow it will rain” and E2=E2=“Tomorrow it will be sunny”.

We know that certainty has probability 1, so if we sum probabilities of events E1E1“Tomorrow it will rain” and E11E11“Tomorrow it won't rain”, we have

P(E1)=0.73P(E1)=0.73

P(E11)=1−0.73=0.27P(E11)=1−0.73=0.27

Now, when it's sunny, it means that it doesn't rain, so event E2E2is included in event E11E11and its probability must be less than this
