To compute $d_1$ and $d_2$, first convert the time to maturity into years. Then substitute the given parameters into the formula for $d_1$: $d_1 = \frac{\ln(S_0/X) + (r + \sigma^2/2)T}{\sigma\sqrt{T}}$.

Conditions: The parameters are $S_0=60$, $X=65$, $r=11\%$, $\sigma=45\%$, and maturity is 4 months.; Time $T$ must be expressed in years, so $T = 4/12$.; Values of $d_1$ and $d_2$ must be rounded to the nearest hundredth before table lookup.
