If the events are independent then you can multiply the individual probabilities. But if they are not, you have to use conditional probabilities.

How do you find the probability of the complement of an event?

The probability of the complement of an event, i.e. of the event not happening, is 1 minus the probability of the event.


How do you find experimental-probability?

To find the experimental probability of an event you carry out an experiment or trial a very large number of times. The experimental probability is the proportion of these in which the event occurs.

What does it mean to find the compliment of the probability of an event?

The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.


How do you find probability using 4 colors of marbles?

The answer depends on the probability of WHICH event you want to find!


If the odds against an event are 9.8 find the probability that the event will occur?

Odds against A = Probabillity against A / Probability for A Odds against A = (1 - Probabillity for A) / Probability for A 9.8 = (1 - Probabillity for A) / Probability for A 9.8 * Probability for A = 1 - Probability for A 10.8 * Probability for A = 1 Probability for A = 1 / 10.8 Probability for A = 0.0926


What is the probability of an event not occurring?

Well, isn't that just a happy little question! When we talk about the probability of an event not occurring, we're looking at the complement of that event. To find this probability, we simply subtract the probability of the event happening from 1. Remember, there are always happy accidents in math, so don't be afraid to explore and make mistakes along the way!


How can you use odd to find probability?

Odds of A to B in favour of an event states that for every A times an event occurs, the event does not occur B times. So, out of (A+B) trials, A are favourable to the event. that is, the probability of A is A/(A+B).

How can you find the probability of a simple event if the total number equally likely outcomes is 20?

How do you find the experimental probability?

To find the experimental probability of an event, you divide the number of times the event occurs by the total number of trials conducted. For example, if an event happens 15 times in 100 trials, the experimental probability would be 15/100, or 0.15. This approach provides an estimate of the likelihood of the event based on actual results rather than theoretical predictions.


What formula is used to find the theoretical probability of an event?

Expected successes= Theoretical Probability · Trials P(event) = Number of possible out comes divided by total number of possible
