Question: 1.) Let X be distributed as a normal distribution with a mean of 10 and a variance of 4. i.) What is P(X > 14

1.) Let X be distributed as a normal distribution with a mean of 10 and a variance of 4. i.) What is P(X > 14 | X > 10)? ii.) If we could alter the variance (right now it's 4), how large could the variance be such that P(X > 8) is no more than 60.26%? [The setup is P(X > 8) 0.6026 and solve for the variance.]
