The probability of getting tails on a coin is SMALLER than rolling a number greater than 2
The probability of getting a six on a six sided die and then getting a tails is zero. There is no tails on a die.
It depends on what variable the probability ratio was for! The random variable could have been the number of heads minus the number of tails, for example.
The probability of getting all tails is 1/25 = 1/32
Since each event is independent, the probability remains at 0.5.

The probability of getting a six on a six sided die and then getting a tails is zero. There is no tails on a die.
The side heads is slightly heavier giving it a greater likely hood of landing on tails.
1 in 2.
The probability of getting all tails is 1/25 = 1/32
It depends on what variable the probability ratio was for! The random variable could have been the number of heads minus the number of tails, for example.
Since the probability of getting tails is 50% or 0.5, the probability of three tails would be 0.5*0.5*0.5=0.125 or 12.5 %
The probability of getting zero tails is 1/2. The probability of getting zero tails twice in a row is 1/2 x 1/2 = 1/4. The probability of getting zero tails three times in a row is 1/2 x 1/2 x 1/2 = 1/8, etc... .
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 of one event or the other occurring is the probability of one plus the probability of the other. The probability of getting 3 heads is the probability of 3 heads (1/23) multiplied by the probability of 4 tails (1/24) multiplied by the number of possible ways this could happen. This is 7c3 or 35. Thus the probability of 3 heads is 0.2734375. The probability of 2 tails is the probability of 2 tails (1/22) multiplied by the probability of 5 heads (1/25) multiplied by the number of ways this could happen. That is 7c5 or 21. Thus the probability of 2 tails is 0.1640625 The probability of one or the other is the sum of their probabilities: 0.1640625 + 0.2734375 = 0.4375 Thus the probability of getting 3 heads or 2 tails is 0.4375.
The probability is 1/4
Since each event is independent, the probability remains at 0.5.
