Calculate the probability of the following coin flip

HHT

Coin Toss Probability Formula

Probability of each coin toss is 1/2, so we have:

P(HHT)  =  1 x 1 x 1
  2 x 2 x 2

P(HHT)  =  1
  8

P(HHT) = 0.125

Calculate the probability of the following coin flip

HTH

Coin Toss Probability Formula

Probability of each coin toss is 1/2, so we have:

P(HTH)  =  1 x 1 x 1
  2 x 2 x 2

P(HTH)  =  1
  8

P(HTH) = 0.125

Calculate the probability of the following coin flip

THH

Coin Toss Probability Formula

Probability of each coin toss is 1/2, so we have:

P(THH)  =  1 x 1 x 1
  2 x 2 x 2

P(THH)  =  1
  8

P(THH) = 0.125

Calculate the probability of the following coin flip

HHH

Coin Toss Probability Formula

Probability of each coin toss is 1/2, so we have:

P(HHH)  =  1 x 1 x 1
  2 x 2 x 2

P(HHH)  =  1
  8

P(HHH) = 0.125


Calculate final probability:

P(3 coin tosses with at least 2 heads)  =  1 + 1 + 1 + 1
  8

P(3 coin tosses with at least 2 heads)  =  4
  8

Our fraction portion is not reduced down completely. Using our GCF calculator, we see the Greatest Common Factor (GCF) of (4 and 8) is 4

Reducing top and bottom by 4, we get:

P(3 coin tosses with at least 2 heads)  =  1
  2

Final Answers

P(3 coin tosses with at least 2 heads) = 0.5


What is the Answer?

P(3 coin tosses with at least 2 heads) = 0.5
