(b)	What kind of probability is this?
	Subjective Classical Empirical

Answer 1

Answer:

a)

Given,

Total number of days = 117

Number of days Phil has his shadow = 106

Now consider,

Probability that Phil will see his shadow on a randomly chosen Groundhog Day is given as the ratio of number of days Phil has his shadow to that of total number of days

i.e.,

= Number of days Phil has his shadow / Total number of days

= 106 / 117

= 0.90598

Required probability = 0.9060

b)

Here it is a Empirical kind of probability.

It is due to that the event doesn't appear i.e., It is attempting to appraise whether it will occur.
