Question:
A formula we gave for conditional probability is
P(E2|E1) = n(E1 and E2)/n(E1)
This formula may be derived from the formula
P(E2|E1) = P(E1 and E2)/P(E1)
Can you explain why? [Consider what happens to the denominators of P(E1 and E2) and P(E1), when they are expressed as fractions and the fractions are divided out.]
