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

1.21K 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.

Because probabilities work with multiplications, not sums.

If ten 7% chances were the same as a 70% chance, then 2 coin flips (two 50% chances) would be 100% heads AND 100% tails which is obviously not the case.
