# What is the probability of getting exactly 2 heads in 4 coin tosses?

## What is the probability of getting exactly 2 heads in 4 coin tosses?

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

What is the probability of getting exactly 2 heads when tossing a coin price?

Consider all the possible ways to get two heads, HHT,HTHandTHH. There are 2⋅2⋅2=8 possible combinations in total. Therefore, the answer is 3/8.

### What is the probability both coins will turn up heads 4 times in a row?

The probability of getting 4 heads in a row is 1/2 of that, or 1/16.

How many ways can you flip a coin 4 times?

16 possible outcomes
Suppose we flip a coin four times. Since each flip can come up heads or tails, there are 16 possible outcomes, tabulated below, grouped by the number of heads in the four flips.

#### What is the probability of flipping a coin 4 times and getting 4 heads?

1/16
The probability is therefore 1/16. N=4: There is only one possible outcome that gives 4 heads, namely when each flip results in a head. The probability is therefore 1/16.

What is the probability of at least two heads?

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 flipping a coin 4 times and getting at least 2 tails?

Explanation: There are 24=16 possible outcomes when you flip a coin four times. Of these outcomes, 11 have two or more tails: {TTTT,TTTH,TTHT,THTT,HTTT,TTHH,THTH,THHT,HTTH,HTHT,HHTT} . Assuming these outcomes are equally likely (the coin is “fair”) gives a probability of 1116=0.6875 .

What is the probability of getting exactly 4 heads when flipping 10 fair coins?

The probability is approximately 20.51%.

### What is the probability of getting at least 3 heads when flipping 4 coins?

What is the probability of flipping exactly 3 heads when flipping a coin 4 times?

N=3: To get 3 heads, means that one gets only one tail. This tail can be either the 1st coin, the 2nd coin, the 3rd, or the 4th coin. Thus there are only 4 outcomes which have three heads. The probability is 4/16 = 1/4.

## What is the probability of getting 2 heads in 4 coin tosses?

0.69 is the probability of getting 2 Heads in 4 tosses. Exactly 2 heads in 4 Coin Flips The ratio of successful events A = 6 to total number of possible combinations of sample space S = 16 is the probability of 2 heads in 4 coin tosses.

What happens if you toss 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. Therefore, total numbers of outcome are 2 2 = 4.
