The correct order is: the probability of heads on 2nd and 4th toss only; the probability of at least 3 tails in a row; the probability of 3 or more heads; the probability of consecutive tails; and the probability of at least 2 tails.
There are 16 outcomes in the sample space.
There are 8 ways of having consecutive tails; this gives the probability 8/16. There is 1 way of having heads on the 2nd and 4th toss only, making the probability 1/16. There are 3 ways to have at least 3 tails in a row, making the probability 3/16. There are 11 ways to have at least 2 tails, making the probability 11/16. There are 5 ways to have at least 3 heads, making the probability 5/16.
