Question

difference between chance and possibility.

Answer 1

chance means that there is something which you could do while possibility means there can be anything

Answer 2

Chance is a part of our everyday lives. 
Probability is defined as the branch of mathematics that describes the pattern of chance outcomes. 

Everyday we make judgements based on probability: 

There is a 90% chance the Bulls will win the game tomorrow. 
There is a sixty percent chance of thunderstorm this afternoon. 
We have a 50-50 chance of winning the game. 
There is a 20% chance of rain today. 

Although we assign certain probabilities to certain events, others might assign different probabilities to those same events due to their difference of opinion. For example, not everyone agrees with the high chance of the Bulls winning the game. They might say that there is a 20% chance the Bulls will win the game tomorrow. It all depends on what the person believes. Chance may result from human design such as casino games and the lottery, or it may result from nature such as determining a person’s sex and other human characteristics.
