The Mayan and other Mesoamerican cultures used a vigesimal number system based on base 20 (and, to some extent, base 5), probably originally developed from counting on fingers and toes. The numerals consisted of only three symbols: zero, represented as a shell shape; one, a dot; and five, a bar.

You are told that PA I B) = PBIA). Which statement below must be true?
ivann1987 [24]

Answer:

A and B are equally likely

Explanation:

The conditional probability is defined as follows:

P(X|Y)=\frac{P(X\cap Y)}{P(Y)}

where:

P(X|Y) is the probability for X to occur, given that Y has occurred

P(X\cap Y) is the probability that both X and Y occur at the same time

P(Y) is the probability for Y to occur

Given two events A and B, we have:

P(A|B)=\frac{P(A\cap B)}{P(B)}

and

P(B|A)=\frac{P(A\cap B)}{P(A)}

In this problem, we are told that

P(A|B)=P(B|A)

Which means that:

\frac{P(A\cap B)}{P(B)}=\frac{P(A\cap B)}{P(A)}

Simplifying, we get:

P(A)=P(B)

which means that A and B are equally likely.
