A toss-up state refers to a state in the United States where both major political parties have nearly equal chances of winning an election, making the outcome highly uncertain. These states are often critical in presidential elections, as they can swing either way and significantly impact the overall results. Political analysts closely monitor toss-up states to gauge election trends and voter sentiment.

No, when you toss a coin there is a 50 percent chance it will land heads up.
The actual number of times 4 comes up is impossible to find, but the expected value of 4 coming up if you toss a 6-sided die 30 times is 5 times.
Because only the second toss matters and there's 2 sides it can land on, the chance your second toss will be tails; will still be 50%. If you want both coins to turn up as tails it would be 0,50 x 0,50 = 0,25 x 100% = 25% chance for both to be tails.
Knowing the results in advance, there is a 7/10 chance that the first toss is heads. In this case "seven out of ten" is quite literal. The first toss is one of the 10, and 7 of them came up heads, so 7/10 is the chance that this particular one is one of the heads.
If you toss them enough times, the probability is 1. For just one toss the probability is 1/4.
