What is the probability of flipping a coin 20 times and getting 1 tails and 1 heads?
None, since that would imply that in 18 cases the coin did not show heads or tails!
Bill will toss a coin and roll a number cube once. What is the probability that the coin will show tails and the number cube will show a multiple of three?
(1/2)*(2/6) = 1/6
What is the probability of flipping 2 coins and having both show heads?
If both tosses are fair, the probability of that outcome is one in four.
Why do complementary events always have a probability of one?
If an event is absolutely certain to happen is then we say the probability of it happening is 1.Complementary events are such that one of the events musthappen. Therefore the probability of one of a set of complementary events occurring is 1.For instance : The probability that a fair coin when tossed will come down showing heads is 1/2, and that it will show tails is also 1/2.The two events are complementary so the probability that the coin toss will result in either a heads or a tails is 1.Similarly, the probability that a die when rolled will show a number 1, 2, 3, 4, 5 or 6 is 1 as all six events are complementary.
What is the probability of tossing three coins and having them exactly one of them show tails?

If you flip a coin to determine the pizza if the coin sHow is heads the pizza is garlic if the coin is tails the pizza is cheese what is the probability that the pizza would be garlic on two consecuti?
The flip of a fair coin is 0.5 heads and tails, so you want the probability of head & head. This probability of garlic, garlic two consecutive tosses is 0.5 * 0.5 = 0.25.
If you flip a coin 100 times and heads show 40 times what are the odds for flipping head?
50/50 50/50? This is equal to 1 which would imply the probability of flipping a head is certain. Obviously not correct as the probability of flipping a head in a fair dice is 1/2 or 0.5
Bill will toss a coin and roll a number cube once. What is the probability that the coin will show tails and the number cube will show a multiple of three?
(1/2)*(2/6) = 1/6
Which numbers show an element of the sample space for first rolling a die and then tossing a coin?
(1,2,3,4,5,6][Heads,Tails] is a depiction of this notation. It is an expression of probability.
What is a biased coin probability?
A biased probability is one where not every outcome has the same chance of occurring. A biased coin is one where one side, the "heads" or "tails" has a greater probability than the other of showing. A coin which has a centre of gravity closer to the tails side than the heads side would be biased in that heads is more likely to show than tails. The size of coin can have an effect on the probability of heads and tails - during the Royal Institute Christmas lectures in the 1990s demonstrating probability a large version of the pound coin was made to be able to allow the audience to see it being tossed - on the broadcast (and tape) version it landed and stayed on its edge! showing the probability of heads = tails ≠ ½; the probability of heads = probability of tails, but they are actually slightly less than ½ as the coin could land on its edge and stay there - with a standard size coin, if it lands on its edge it takes very little for the centre of gravity to shift outside the base of the edge and for the coin to fall over, but with a very large similar coin (ie one scaled up [proportionally] in lengths) it can take quite a bit before the centre of gravity goes outside the base if it lands on its edge which forces it to fall over (plus there will be a "significant" rise in the centre of gravity to do so, thus favouring stability on an edge which does not exist in the standard, small, sized version of the coin).

What is the probability of tossing three coins and having all of them show tails?
When we toss a coin getting head or tail have equal probability of 50% - that is, out of the two possible outcomes getting the specified one becomes 1/2 probability. When we toss three coins, the probability of getting all the coins showing tails is given by (1/2) * (1/2) * (1/2) equal to 1/8 or 12.5 % chance. Alikban

2 out of 8
