3.  Question  :  I am tossing this coin. Can you say whether it will show up Heads or Tails?  
Reply  :  The coin may show up either Heads or Tails. Both have a equal chance of occurrence. 50% for Heads and 50% for tails.  
Reply reframed  :  The probability for the coin to show up heads is 0.5 and to show up tails is 0.5  
The event here can be assumed in two ways
 
Reply reframed  :  The probability for the coin not to show up heads is 0.5 and not to show up tails is 0.5  
The event here can be assumed in two ways
 
4.  Question  :  There are 10 balls in this bag, 4 of them red and 6 blue. I am picking up one ball. Will it be red or blue?

Reply reframed  :  The probability for the ball drawn to be red is 0.4  
 
Reply reframed  :  The probability for the ball drawn to be blue is 0.6  

Occurrence » The three possibilities  For Sure or Always  Never  May or may not 
This expressed in probability terms would be "The probability of happening of the event is 1"

4.  Question  :  I am throwing up a die. Can you say whether I would get any of the numbers 1,2,3,4,5,6 or not. 
Reply  :  What else would appear? Since the six faces of the dice will have the numbers 1,2,3,4,5,6 on them, one of these should appear for sure. There is a 100% chance that one of the numbers 1,2,3,4,5,6 would appear.  
Reply reframed  :  The probability for the die to show up either 1,2,3,4,5 or 6 is 1. 
This expressed in probability terms would be "The probability of the happening of the event is 0".
1.  Question  :  How did you write your exams?

4.  Question  :  I am throwing up a die. Can you say whether I would get a multiple of 10 or not. numbers 1,2,3,4,5,6 or not. 
Reply  :  How can you expect to get the number 10 on the dice? The six faces of the dice have the numbers 1,2,3,4,5,6 on them and only one of those would appear. There is a 0% chance that the number appearing is a multiple of 10.  
Reply reframed  :  The probability for the die to show up a multiple of 10 is 0. 
How much is "x"?
It would be dependent on the case in consideration.
This expressed in probability terms would be "The probability of its happening is p [p = x ÷ 100]"

Probability of an event is an indication of
Probability is a numeric value which lies between the two extremes, 0 and 1 both numbers inclusive.
200%, 300%,.... 1000% Chance!! 
When something happens for sure, it is 100% and when it does not happen it is 0% and when it has a certain likelihood of occurrence somewhere in between these extremes it is between 0% and 100% and never 200%, 300%, 500% etc.
Something more than 100% in expressing the possibility of happening of an event should be understood as a qualitative measure rather than a quantitative measure.
