Final answer:
The minimum number of successes (heads) you can get when flipping 4 coins is 0, and this occurs if all coins land on tails. The outcomes of flipping two coins include combinations of heads and tails, each with its own probability.
Step-by-step explanation:
The minimum number of successes you can get in any flip of 4 coins, where success is defined as landing on heads, is 0. This outcome is possible if all four coins land tails (TTTT), which is one of the possible combinations when flipping coins. Each individual coin has a 50 percent chance of landing on heads and a 50 percent chance of landing on tails, regardless of the previous outcomes.
When flipping two fair coins, various events can be considered for different probabilities. For example, the event of getting at most one tail (zero or one tail) could be represented as F, the event of getting two faces that are the same could be G, and the event of getting a head on the first flip followed by a head or tail on the second flip could be H. Each of these represents a different scenario within the sample space of flipping two coins, which consists of four outcomes: HH, HT, TH, TT.
