one out of 5 or 2 out of 10
It is 60/100 = 0.6
The probability of tossing a coin 5 times and getting all tails is:P(TTTTT) = (1/2)5 = 0.03125 ≈ 3.13%
Since each event is independent, the probability remains at 0.5.
The probability of tossing a coin twice and getting tails both times is 1 in 4, or 25%. If you have already tossed a coin and had it land on tails, the probability that it will land on tails again the next time you toss it is 50%.

The probability is 0.998
The probability of Tails on the first toss is 0.5 .The probability of Tails on the second toss is 0.5 .The probability of Tails on the third toss is 0.5 .The probability of Tails on the fourth toss is 0.5 .The probability of all four is (0.5 x 0.5 x 0.5 x 0.5) = 0.0625 = 6.25%
It may be that you don't have a "fair coin", or it might just be chance. To be sure - or rather, reasonably sure - you need to try tossing it quite a bit more times.
Because a coin is two-sided, 50/50 is always the probability. Unless your coin lands on the grass (on the lawn), then it will probably land on its edge.
