Out of the 16 possible outcomes for a coin tossed four times, 4 of them result in 3 Tails & 1 Head. They are: TTTH, TTHT, THTT, and HTTT.
The term 'sample space' can be somewhat arbitrary. In this case, it might be any of the following (or another) possibility: If order of flips is significant: HHHH HHHT HHTH HHTT HTHH HTHT HTTH HTTT THHH THHT THTH THTT TTHH TTHT TTTH TTTT If order is not significant: HHHH HHHT HHTT HTTT TTTT If, say, only the number of either heads or tails is important: 4 3 2 1
There are 16 permutations of a coin tossed 4 times. They are ...HHHH - HHHT - HHTH - HHTTHTHH - HTHT - HTTH - HTTTTHHH - THHT - THTH - THTTTTHH - TTHT - TTTH - TTTT... and the permutations with only one tail are bolded. There are 4, so the probability of flipping a coin 4 times and getting only 1 tail is 4 in 16, or 1 in 4, or 0.25.The coin does not have a memory therefore the probability is always 50/50.
There is 24 or 16 outcomes. There is 4 ways to get heads once (HTTT & THTT & TTHT & TTTH). So, the probability of getting heads only once if a fair coin is tossed 4 times is 4/16 or 1/4.
Mean is the average.
It mean what you don't what does it mean.
'Mean' is the mathematical word for 'average'. 'Average' is the everyday word for 'mean'.
