The model is:

$log\left(\frac{P(Y = 1)}{P(Y = 0)} \right ) = -6.38 - 2.73 * treatment + 0.14 * anxiety$

Which can be tranformed to:

$P(Y = 1) = \frac{e^{-6.38 - 2.73 * treatment + 0.14 * anxiety}}{1+e^{-6.38 - 2.73 * treatment + 0.14 * anxiety}} $

$= \frac{e^{-6.38 - 2.73 * 0 + 0.14 * 70}}{1+e^{-6.38 - 2.73 * 0 + 0.14 * 70}} $

$= \frac{e^{3.42}}{1+e^{3.42}} $

$= \frac{30.56942}{31.56942}$

$=0.9683238$

So the first answer is correct.
