Answer: organized list of sample space =[ HHH, HHT, HTH, THH, HTT, THT, TTH and TTT]
Event at least two tails =[HTT, THT, TTH, and TTT]
Probability (at least two tails) = 1/2 or 0.5
Step-by-step explanation:
A coin has two sides: Head (H) and Tail (T)
When three coins are flipped, the total outcome for sample space for this experiment are:
[ HHH, HHT, HTH, THH, HTT, THT, TTH and TTT]
Outcome that represents at least two tails means outcome that has 2 tails or more, they are: [ HTT, THT, TTH, and TTT)
Probability that there will be at least two tails: here, probability is calculated as number of possible outcomes/ total number of outcomes.
Total number of outcomes = 8
Number of Possible outcomes = 4
Pr (at least two tails) = 4/8
= 1/2 in simplest fraction form or 0.5 as decimal.
I hope this helps, please mark as brainliest answer.
