What is the probability of getting at least one head when 4 coins are tossed?

1/16
In counting the number of heads in 4 coin flips, the probability that we get exactly one head is the probability that we get anyone of the following 4 outcomes: HTTT, THTT, TTHT, or TTTH. Each has probability 1/16, so the probability to get exactly one head in 4 flips is 1/16 + 1/16 + 1/16 + 1/16 = 4/16 = 1/4.

What is the probability of getting all heads with 4 coins?

The probability of one coin coming heads (assuming a fair coin) is 1/2. So the probability of 4 independent fair coins showing all heads is (1/2)^4 = 1/16.

What is the probability of the result of 4 independent coin flips being exactly 1 head and 3 tails?

Originally Answered: A coin is tossed 4 times. What is the probability of getting exactly 3 heads when it lands? From the 16 possible outcomes, 4 have exactly 1 tail (equivalent to 3 heads). Therefore 4/16=25% of the time exactly 3 heads will be obtained.

What is the sample space of tossing 4 coins?

Hope it clarifies. Every time you toss a coin, there are two possibilities H or T. As one coin is tossed four times, each toss is independent of other. If we note down four outcomes of four tosses then there will be 2^4 = 16 possible outcomes.
