How confident do you need to be that a woman will say yes before you ask her out?

And for the ladies, please answer from a female perspective

I have to be 100% sure she will say yes (she told me to ask her out)
90% sure she will say yes
80% sure she will say yes
60-70% sure she will say yes
40-50% sure she will say yes
20-30% sure she will say yes
Only 0-10% sure and I will ask her out/I’m always asking out women
