Three fair coins are tossed independently. T is the event that two or more…

Answer: 0

Reason:

• List all 8 equally likely outcomes for three fair coins: HHH, HHT, HTH, THH, HTT, THT, TTH, TTT.

• Event 'two or more heads' occurs for: HHH, HHT, HTH, THH.

• Event 'two or more tails' occurs for: TTT, HTT, THT, TTH.

• There are no outcomes that appear in both lists, so the intersection is empty.

• Alternatively: requiring at least two heads and at least two tails would require at least four tosses, which is impossible with three tosses.

Therefore the probability of the intersection is 0.
