what is probability?? Why do we need to find this?? What is furmulae to find this?? I am in 8th grade and this topic will comein my olympiad and I am not prepared well. So.. please help me...

When solving more complicated probability problems, we may need to consider series of random experiments or experiments that involve several different aspects, such as drawing two cards from a deck or rolling several dice. In such cases, the ability to calculate relative frequencies (and thus probabilities) requires counting the number of possible outcomes of the experiment. Although counting the number of possible outcomes for simple random experiments, such as the flip of a coin (heads or tails), may be quite simple, counting the number of possible outcomes for the ordered selection of three cards from a standard deck may not be. We will show you how to handle these more complicated counting problems, thereby expanding your ability to solve a range of statistics problems.that is why we use probability. as for you just the formula is required right now.that is
total no. of possible outcomes/tot. no. of observations
Answer:
Probability = possible outcome/ Total no. of possible outcome
Step-by-step explanation:
Probability is the possible or favorable outcome out of the total outcomes. For example, if you toss a coin, there is probability of getting head and tail is 50%. In this type of situation we need to find the probability to know the chance of getting desirable outcomes.
Formula,
Probability = Possible outcome/ Total no. of possible outcome
