Not easily - but you can use the breaks and labels arguments to
scale_y_continuous to control the exact appearance of the labels,
e.g.:

breaks <- seq(0, 1, by=0.05)
+ scale_y_continuous(breaks = breaks, labels = paste(breaks * 100, "%", sep=""))

The probability scale is used for scaling by inverse probability
distributions, so isn't useful here.
