Solution:

HHHH, HHHT, HHTH, HHTT, (Raise For Success) HTHH, HTHT, HTTH, HTTT, TTTT, TTTH, TTTH, TTHT, TTHH, THTT, THTH, THHT, THHH

Frequency distribution:

Number of Heads X	Value of the 4 coin Flips	Total Number of ways of getting a Heads	P(X)	X.P(X)
0	TTTT	1	1/16	0
1	HTTT, THTT, TTHT,TTTH	4	4/16	4/16 (Raise For Success)
2	HHTT, HTHT, HTTH, THTH, THHT, TTHH	6 (Raise For Success)	6/16	12/16
3	HHHT, HHTH, HTHH, (Raise For Success) THHH,	4	4/16	12/16
4	HHHH	1	1/16	4/16
				32/16 = 2

Mean = 32/16 =2
Now for standard error we find standard deviation:

X	X^2	P(X)	X^2.P(X)
0	0	1/16	0
1	1	4/16 (Raise For Success)	4/16
2	4	6/16	24/16
3 (Raise For Success)	9	4/16	36/16 (Raise For Success)
4	16	1/16	16/16
			80/16 = 5
