Enough to kill. 100 to 200 milliamps (0.1 to 0.2 amps) will cause ventricular fibrillation, which can cause death.

Surprisingly, above 200 milliamps may actually save your life.
Perhaps, that small amount could work if directly applied to the heart but in this case it wasn’t and the water in the tub would deflect the current. Most likely she was hit with 20+ amps at 110v.
I saw Goldfinger, so I’m an expert.
