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

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.

Depending on what you meant. They could be the same or different.

If you have 1 – 10 numbered on marbles and just need to pull 1-7, then each one has a 10% chance for a collective 70%

If you are talking about making attempts at something over and over you multiply the odds against each other.

(7% x 7% x 7%) = .0343% chance you hit 3 times in a row.

If you just want to win once then it’s slightly backwards, calculate the odds of failing over and over then flip it.

100% – [(100% – 7%) * (100% – 7%) etc. ]
