Why is a single 70% chance different to Ten 7% chances

1.16K views

Like. I know they are different and that one is less likely. But could someone explain this in a way that I can explain it to my partner? I know it is true but cannot remember anything about why and how to explain my point.

Think about it like this: If something has a 70% chance of occurring then it has a 30% chance of not occurring. If something has a 7% chance of occurring it has a 93% chance of not occurring. If you have multiple trials of something the chance that it does not happen is the chance of not happening times itself for each trial. 10 trials with a 7% outcome has a 39.8% chance of happening (since 93%^10 =60.2%)
