The probability of getting tails on a coin is SMALLER than rolling a number greater than 2
The probability of rolling any number on a cube can be represented by the formula: X / the number of variables. Since any cube has 6 sides, the probability of rolling any of the numbers 1 through 6 on the cube, can be represented by the formula: X = 1 / 6 = 16.66% The odds or probability of flipping a coin and landing it on either side can be represented by X = the requested result / the number of variables = 1 /2 = 50% Therefore, given the two questions of probability, there is a much greater chance of landing a coin on "tails" rather than rolling a "4".
The probability of flipping three tails with three coins is (1 in 2)3 or 1 in 8 or 0.125.
The probability of getting all tails is 1/25 = 1/32
If they are fair coins, the probability is 0.25
For a normal coin, it is 0.5.
Complementary events are events that are the complete opposite. The compliment of event A is everything that is not event A. For example, the complementary event of flipping heads on a coin would be flipping tails. The complementary event of rolling a 1 or a 2 on a six-sided die would be rolling a 3, 4, 5, or 6. (The probability of A compliment is equal to 1 minus the probability of A.)
1/2 if the quarter is 'fair'.
The probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 1/8.
