Probability - Example
Scenario
Consider a scenario where three coins are tossed simultaneously. What is the probability of at least one being heads?
Solution
Sample Space
S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT}
n(S)=8
Event
E= Getting at least one heads
E={HHH, HHT, HTH, THH, HTT, THT,TTH}
n(E)=7
Probability
$$ P(E) = \frac{n(E)}{n(S)}$$ $$P(\text{getting one heads}) = \frac{7}{8} $$
