Using the formula from above:. Probability formula applied. Probability of rolling an even number? The formula and solution. The probability of an event can only be between 0 and 1 and can also be written as a percentage. The probability of event A A A A is often written as P A P A P A P, left parenthesis, A, right parenthesis.

Posted 6 years ago. A card is drawn from a standard deck of 52 cards. Find the probability that is a. a heart or a face card. a jack or an ace card c. a 10 or a spade. Avinash Athota. I am just warning you, I don't know much about cards that much, so my numbers may be off. there are 13 heart cards and 12 face cards aces aren't faces, right? Comment Button navigates to signup page. Posted 2 years ago. Can't you multiply the possibility fraction with the the same numerator or denominator to get a different but equivalent answer? Andrew H. Direct link to Andrew H. Yes you can multiply probabilities with fractions that are equal to one. We usually want the fraction in the simpliest form though. does probability always have to be written like a fraction? How do you know when to write it as a percentage?

Usually, the question concerning probability should specify if they want either fractions or percentages. I've also seen them state which form to use in italics right after the question. Hope this helps! Posted 4 years ago. If there were 3 black dogs,4 brown dogs,and 2 white dog what would happen if You took 2 brown dogs away. Posted a year ago. there would be 7 dog there would be 7 dogs instead of 9. And there would only be 2 brown dogs now. Which is equal to the number of white dogs. Or is there a more complex reason to this? I don't know.
