If you toss five fair coins, in how many ways can you obtain at least one tail?

Expert Solution

Total number of outcomes for tossing 5 coins = 2⁵ = 32

Number of ways to obtain zero tail = Outcomes where all coin lands up in head = 1

Number of ways to obtain at least one tail = Total number of outcomes for tossing 5 coins - Number of ways to obtain zero tail

= 32 - 1

= 31 (ans)
