GUYS I REALLY NEED HELP FAST T^T WORTH 19 POINTS
Three coins are flipped. Make an organized list of the sample space for this experiment. Which outcomes represent the event “at least two tails”? What is the probability that there will be at least two tails?

1. 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.

P(atleast 2 tails) = 4/9

Step-by-step explanation:

(H H H)

(H H T)

(H T H)

(T H H)

(T T H)

(T H T)

(H T T)

(T T T)

Last 4 are atleast 2 tails
