# Symbol for 'equally likely/probable'

I'm looking for the 'mathematical' symbol, if it exists, that denotes 'equally likely'. For example, one has two potential outcomes from a present state, both of which are equally likely (or probable). Is there a symbol for that?

• Won't "$=$" do, when suitably applied?

• I agree with @whuber. You usually see P(outcome A | current state) = P(outcome B | current state). It is more of a mathematical statement than a symbol. Feb 24 at 19:55
• @RCarnell, why not turn your comment into an official answer? That way this thread won't count as unanswered. Apr 22 at 8:19
• Couple distinctions: are the two outcomes complementary like heads versus tails on a fair coin? Also you mention "state", is this actually a dynamical system state (that is otherwise random) or more simply an assumption (like that the coin is in fact fair)? Apr 23 at 17:55

$$P(\text{Event A} | \text{current state}) = P(\text{Event B} | \text{current state})$$ to denote outcomes that are equally probable.
