Good videos, very helpful - from UK

@lqing1984 ; the (.98) came from (.2)-(.100) . you have to do that because thats how you find the probability of A NOT happening, which would be (.98)

[Paleoint]

How do you know whether to attack the problem by looking at the probability that it WILL happen, or as you did in taking 1 - P(it won't happen).

[lqing1984]

sorry, i don't know where do you get 0.98 from?

[Jose Alberto Patino]

At least 2:

P(Exactly one) + P(At least one)
