How to find the probability of something.

If something has a high probability, it is likely to happen. Probabilities are most commonly shown as fractions. The probability of getting 'tails' when you toss a coin is a 1 in 2 chance, or 1/2.Turning left and turning right are Mutually Exclusive (you can't do both at the same time) Tossing a coin: Heads and Tails are Mutually Exclusive. Cards: Kings and Aces are Mutually Exclusive. What is not Mutually Exclusive: Turning left and scratching your head can happen at the same time. Kings and Hearts, because we can have …If P is the probability of an event occurring, then: 1 − P ⋅ is the probability of the event not occurring. The odds will then be: P 1 − P ⇒ 5 8 1 − (5 8) = 5 8 3 8 = 5 3. To make this clearer: The probability of throwing a 6 with a standard die is 1 …
