Find the set of outcomes that occur when we flip 3 coins and obtain at least two heads. Enter the outcomes using H and T to represent heads and tails respectively. For example, an outcome of two heads tosses followed by one tails toss would be HHT. (Use a comma to separate answers as needed.)

Solution

If 3 coins are flipped the outcomes are ,

n(s) = 2³ = 8

S = { HHH , HHT , HTH , HTT , THH , THT , TTH , TTT }

Set of outcomes that occur when flip 3 coins and obtain atleast two heads = { HHH , HHT , HTH , THH }
