Thanks.

Is it accurate to say, more simply (simplicity being a high priority here), that 'we play with the probabilities' of collapse to one basis state or to the other - thus skipping the need to explain linear combinations or coefficients?

Well, all the playing happens with the positive/negative coefficients. Without explaining that you can cancel them out with each other, it will not be clear how all-positive probabilities collapse to some basis states.

In fact, classical stochastic computational models have exactly this deficiency. You can't pump up probabilities of some unknown states. They can only tend towards a uniform mixture.

Everything is in the minus sign.
