Four coins are tossed. How many outcomes are possible?
8 outcomes are possible in this situtation. You just have to multiply 4 by 2 to get the answer.
If you toss a coin four times how many possible outcomes are there?
24 or 16
How many possible outcomes are there if you toss a fair coin four times?
Normally there would considered to be 2⁴ = 16 possible outcomes as each outcome is one of 2 states: Head or Tails. ------------------------- There is an extremely small probability that a normal coin will end up on its edge, which mean there are 3⁴ = 81 possible outcomes. However, this probability is so small that it is ignored and normally only 2 outcomes are considered possible. As the radius to width ratio of the coin changes, the probability of the coin ending up on its edge changes, for some values being so significant that it becomes a real probability that the edge can result, and for some ratios it is almost always the edge that results and the probability of head or tails (ie ends of the cylinder that is the coin) is so small as to be ignored like the edge for a normal sized coin (cylinder).
Five coins are tossed How many outcomes have either four heads or four tails?
1/4
Is 3X cubed minus 2X squared a binomial?
No, it isn't. You can express 3x3-2x2 as 3x3-2x2+0x+0, so it actually has four terms. The definition of a binomial is an expression in the form Ax+b, where A and b are constants, so 3x3-2x2 is not a binomial. It is actually a quartomial.
