Have you ever wondered how likely it is that there are aliens in our universe? Or the probability of another planet like Earth existing?

What are the odds? What are the chances? Well, now we can tell you the answer.

Inspired by the most common Google searches when it comes to odds, chances and probabilities, our research has enabled us to give an exact figure for the likelihood of all of our biggest wonders and curiosities ever happening.

The results were quite revealing...

As well as being central to the odds shown in the above infographic, probability is also relevant to popular casino games such as online roulette or online blackjack.

For example, in roulette, an even bet has a 48.6 per cent chance of winning, while a single bet has just a 2.7 per cent chance of winning.  And in blackjack, there is just a 31 per cent chance of busting on 12, compared to a 62 per cent chance of busting at 16.

So, while the bet placed is in the player’s control, the outcome is always affected by the element of chance.

Whether the player ultimately wins or loses money depends on how they weigh their chances. To do this, they must calculate probabilities and wager accordingly.

Methodology

Questions about odds and likelihoods were obtained from Google search suggestions for four seed phrases: "what are the odds", "what are the chances", "how likely", and "what is the probability".

The odds of the events in question were derived from statistics supplied by government agencies, professional bodies and associations, expert panels, academic studies, their coverage in the media, and industry publications.

The odds associated with games were calculated using WolphramAlpha.
