## What is the probability of hitting at least one head when tossing a coin 7 times?

Since the probability of flipping the tails in one roll is 1/2, the probability of flipping seven tails straight is 1/2 to the 7th power, or 1/128. Therefore, the probability of getting at least one head is 1 – 1/128 = 127/128.

## What does at least 1 mean?

one or more “At least one” is a mathematical term which means one or more. It is commonly used in situations where existence can be established but the total number of solutions cannot be determined.

## What is at least the probability?

At least in probability it means that all probabilities that are greater than the stated probabilities. On the other hand, at most, probability means that all probabilities are less than the given probability. So we can say that at most it means the maximum, or at least it means the minimum.

## How many results does at least one head have?

4 possible It may happen that the first coin is heads and all others are heads; or it may be that the other coin is heads and all the rest are heads; or it may be that the third (or fourth) coin is an eagle and all the others are heads. Because they exist 4 possible results with only one head, the probability is 4/16 = 1/4.

## What is the probability of getting at least one tail?

1023/1024 We need to find the probability of getting at least one tail. The probability of hitting at least one tail is one minus the probability of all eagles. Therefore, the probability of getting at least one tail is 1023/1024.

## What is the probability that at least one head will be hit in 5 coin tosses?

The probability of getting 0 eagles is (1/2) to the power of 5 = 1/32. Therefore, the probability of getting at least one head is 31/32.

## What is the probability of getting one head and two heads?

1/4 For example, the probability of two heads is 1/2 ยท 1/2 = 1/4and the probability of two heads is the same. Since there are two leaves corresponding to one head and one tail, each with a probability of 1/4, the probability of this event is 1/4 + 1/4 = 1/2.

## What is the probability of getting at least one six in one throw of three impartial dice?

Question: What is the probability of getting at least one six in one throw of three impartial dice? Answer: The probability of getting 1 or 2 or 3 or 4 or 5 with one die roll is 5/6 x 5/6 x 5/6 for 3 dice = 125/216. This is the probability of getting at least one 6 when rolling 3 dice.
