What is the probability that in tossing a coin 5 times we get 3 heads and tails?

5/16
Summary: If you flip a fair coin 5 times, the probability that you will get exactly 3 tails is 5/16.

What is the probability that exactly two coins landed with heads side up when Roxanne tossed four coins?

Thus the probability is: 2/8=0.25 but the correct answer is 0.375.

What are the possible outcomes in case binomial probability where two coins x and y are tossed simultaneously?

Let us take the experiment of tossing two coins simultaneously: When we toss two coins simultaneously then the possible of outcomes are: (two heads) or (one head and one tail) or (two tails) i.e., in short (H, H) or (H, T) or (T, T) respectively; where H is denoted for head and T is denoted for tail.

What is the probability of getting heads when a coin is tossed?

The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.

What is the probability of rolling a 5 or flipping heads?

The probability of getting heads is 1/2, and the probability of getting 5 or 6 is 1/3, and so you simply multiply 1/2 x 1/3, which is 1/6. Therefore, the probability of getting both a heads and a 5 or 6 is 1/6.

What is the probability of getting 2 heads in 5 tosses?

All the remaining outcomes contain at least 2 heads. Hence 32–6=26 outcomes contains at least two heads. Hence the probability is 26/32.

How many ways to get 3 heads if you flip a coin 5 times?

In this case we are flipping 5 coins — so the number of possibilities is: 2 x 2 x 2 x 2 x 2 = 32.

What is the probability of getting 2 heads or less?

1/2
Answer: If you flip a coin 3 times, the probability of getting at least 2 heads is 1/2.

What is the probability of tossing a coin to your Witcher?

As this coin has two faces on it, his coin toss probability of getting a head is 1. Better not get on the wrong side (or face) of him! We here at Omni Calculator wonder what the odds are that you’ll toss a head to your Witcher…

How many heads does it take to toss a coin?

A fair coin is tossed repeatedly until 5 consecutive heads occurs. What is the expected number of coin tosses? Stack Exchange Network Stack Exchange network consists of 178 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.

How do you find the expected number of heads in probability?

If we get a head then a tail (probability 1 4 ), then the expected number is e + 2. Continue …. If we get 4 heads then a tail, the expected number is e + 5. Finally, if our first 5 tosses are heads, then the expected number is 5. Thus e = 1 2 (e + 1) + 1 4 (e + 2) + 1 8 (e + 3) + 1 16 (e + 4) + 1 32 (e + 5) + 1 32 (5).

How do you calculate the number of times a coin is flipped?

By linearity of expectation, the expected number of coin flips is E (R_ {0+}) + E (R_ {1+}) + \\ldots + E (R_ {4+}). E (R_ {4+}) is 2 E (R_ {5+}) = 2, because one half of the time we flip at least four heads in a row, we go on to flip five heads in a row, i.e. the following coin flip is heads.
