Credence or degree of belief is a statistical term that expresses how much a person believes that a proposition is true.
[1] As an example, a reasonable person will believe with close to 50% credence that a fair coin will land on heads the next time it is flipped (minus the probability that the coin lands on its edge).
Credence is a measure of belief strength, expressed as a percentage.
Credence is closely related to odds, and a person's level of credence is directly related to the odds at which they will place a bet.
[1][2] For example, if Alice is fairly certain that she saw Bob at the grocery store on Monday, then she might say, "I believe with 90% credence that Bob was at the grocery store on Monday."
