Three distinct coins are tossed together. Find the probability of getting:
- at least 2 heads
- at most 2 heads.
Answer:
When three coins are tossed following is the sample space:
{HHH, HHT, HTH, THH, HTT, THT, TTH, TTT}
- P(at least 2 heads) =\( \frac{4}{8} \)
- P(at most 2 heads) = \( \frac{7}{8} \)
