ie was rolled twice. The first time it landed on a number that we will call
“x”. The second time it landed on a number that we will call “y”. We will symbolize some
events as follows:
A: x is odd.
B: x is a prime.
C: y is odd.
D: y is a prime.
Express the following probabilities using the notation “p(. . . )”. For example, the chance
that x and y are both odd may be expressed as p(A ∧ C).
(1) The chance that x is odd and y is even.
(2) The chance that x and y are not both odd (i.e., at least one is even).
(3) The chance that x is a prime given that it is even.
(4) The chance that x is even given that it is a prime.
(5) The chance that x and y are both primes given that they are both odd.
(6) The chance that at least one of x and y is a prime given that at least one of them is odd.
Reid held that philosophy should be based on instinctive commonsense beliefs about sense perception, personal identity, God, free will, and morality. Discuss this claim and explain what those commonsense beliefs might be.
