Let $X$ be a standard normal random variable.
Find the following probabilities:
1. $p_1 = P(X \ge 0)$
2. $p_2 = P(-1.3 \le X \le 0)$
3. $p_3 = P(-1.3 \le X \le -0.65)$
4. $p_4 = P(0.65 \le X \le 1.3)$
Instructions on how to input the answer:
Round your answer to exactly 4 decimal places, even if it is 0 which is expected to be written $0.0000$. Input the string of the answers separated by a comma. Do not include any space in the text.
$(p_1, p_2, p_3, p_4) = (\_)$
