By definition of conditional probability,
P(A | B) = P(A and B) / P(B)
so
P(A and B) = P(A | B) P(B) = 0.5 × 0.58 = 0.29
Answer:
approximately 1.77
So if you want to precisely express its value, you should say “the square root of pi” (or “root pi”). But it's approximately 1.77. In reality, Pi is an unending, never repeating decimal, which means it is an irrational number. Here are the first digits: 3.1415926535897932384626433832795.
