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 probabillity?

Environmental probabilism is the notion that a given environment can be modified in many probable ways for a particular purpose through sound environmental engineering,as opposed to environmental determinism. It is an extention of environmental possibilism.


A number is chosen 1 to 25 find the probabillity of selecting a number greater than 18?

Probability is ratio of the events you want over the total number of events. There are 7 numbers greater than 18 and you have 25 total options, so your probability is 7/25 or 28%.


If you choose two cards from a standard deck what is the probabillity they will be aces?
