Two coins tossed sample space is (H=Heads, T = Tails) as follows. HH, HT, TH, TT is the sample space.

Sample space for two coins tossed is: HH HT TH TT Therefore at most one head is HT TH TT or 3/4 or 0.75.

Assuming the variable of interest is the face on top: H (= heads) or T (= tails), then they are the four possible outcomes: HH, HT, TH and TT.

The sample space is 23 or 8; which can be listed out as: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. There are 2 of the 8 that have exactly 2 heads; so the probability of exactly two coins landing on heads is 2/8 or 1/4.

Coins do not have numbers, there is only the probability of heads or tails.

The sample space for tossing 2 coins is (H = Heads &amp; T = Tails): HH, HT, TH, TT

It is the event that one of the two coins lands showing tails and the other shows heads.

The sample space when tossing 3 coins is [HHH, HHT, HTH, HTT, THH, THT, TTH, TTT]

You find the sample space by enumerating all of the possible outcomes. The sample space for three coins is [TTT, TTH, THT, THH, HTT, HTH, HHT, HHH].

They are:HHH, HHT, HTH, THH, HTT, THT, TTH, TTT.

This question can be rather easily answered, as soon as outcomes 'a' and 'b' are defined.

The answer depends on the experiment: how many coins are tossed, how often, how many dice are rolled, how often.

Simple answer: All coins are graded by the same scale. Circulated coins by how much wear the coin has. Uncirculated coins by how well the coins are struck.
