When a player flips all the 4 quarters, Then 16 Possible outcomes are : HHHH, HHHT, HHTH, HTHH, THHH HHTT, HTTH, TTHH, HTHT, THTH, THHT HTTT, THTT, TTHT, TTTH,TTTT
To earn total of $1 exactly 1 coin should land head. 4 such possible outcomes are: HHHT, HHTH, HTHH, THHH
Therefore required probability =1/4 = 0.25
