# Integrate the cumulative normal distribution calculator?

GROUPS:
 Hello everyone, I am trying to calculate the price option of an option un, which is however i'm struggling in calculating the Cumulative Normal Distribution Calculator. S = 20 K = 25 r = 0.05 d = 0.03 s = .24 T = 3/12 C = S*Exp[-d*T] - K*Exp[-r*T] d1 = (Log[S/K] + (r - d + 1/2*s^2)*T)/(s*Sqrt[T]) d2 = d1 - s*Sqrt[T] Resolve[d1] Resolve[d2] Do you know how to do it?Thank you!
