If 6 coins are tossed, how many different coin sequences will have exactly 3 tails, if all tails have to occur in a row?	Choose one
A) 4  B) 8  C) 16  D) 20  E) 24
xactly 3 tails and have to occur in row   We have 6 coins we use the glue method so we say all 3 tails as 1   so we have 4! ways, however we need to reduce duplicate for 3 Heads as well   HHH{T} therefore using anagram method   4!/3! = 4   4nswer: 4
<result>A</result>
