What is the probability of flipping a coin three times and getting the same result every time?

Three flips of a fair coin Suppose you have a fair coin: this means it has a 50\% chance of landing heads up and a 50\% chance of landing tails up. Suppose you flip it three times and these flips are independent. What is the probability that it lands heads up, then tails up, then heads up? So the answer is 1/8, or 12.5\%.

When a coin is tossed 3 times what is the probability of getting one head?

7/8
Summary: A coin is tossed 3 times. The probability of getting at least one head is 7/8.

When three coins are tossed what is the probability of getting at least one tail?

Probability of NOT getting a tail in 3 coin toss is (12)3=18 . Probability of getting at least 1 tail in 3 coin toss is 1−18=78 .

Is tossed 3 times find out the number of possible outcomes?

(a) In a single throw of a coin there are 2 possible outcomes namely Head (H) and Tail (T). So, by the fundamental principle of multiplication, the total number of possible outcomes in 3 tosses =(2×2×2)=23=8. (i) total number of possible outcomes in 4 losses =(2×2×2×2)=24=16.

What is the probability of tossing 3 coins at random?

Hence the required probability is 3/8. Example 2: In an experiment, three coins are tossed simultaneously at random 250 times. It was found that three heads appeared 70 times, two heads appeared 55 times, one head appeared 75 times and no head appeared 50 times. find the probability of:

What is the total number of outcomes when a coin is tossed?

The total number of outcomes when a coin is tossed 3 times is 2 3 = 8. ⇒ The probability of the outcome of all the three tosses being the same is 2 8 = 1 4. Early symptoms of spinal muscular atrophy may surprise you.

What happens when you toss three coins simultaneously?

We know that when a coin is tossed, the outcomes are head or tail. We can represent head by H and tail by T. Now consider an experiment of tossing three coins simultaneously. The possible outcomes will be HHH, TTT, HTT, THT, TTH, THH, HTH, HHT.

What is the probability of a coin coming up as head?

In case a coin is tossed, then it will either come up as a head or a tail. There is always a probability that either one of them can happen. A probability of zero indicates that the occurrence of event is quite impossible. When a coin is tossed, it would be impossible to acquire both head and the tail at the same time.
