252/1024 or 0.246.
One method of calculating it is this: The total number of outcomes possible by tossing a coin 10 times is 2 to the 10th, which is 1024. In addition, getting 5 heads in 10 tosses is like arranging 5 identical objects in 10 spaces (the remaining 5 spaces are by default Tails), which can be done in 10C5 ways, which is 252. So the probability of getting 5 heads is 252/1024.
0.5
No. It is 1/2.
By tossing two coins the possible outcomes are:H & HH & TT & HT & TThus the probability of getting exactly 1 head is 2 out 4 or 50%. If the question was what is the probability of getting at least 1 head then the probability is 3 out of 4 or 75%
No, the possible results of two coin flips are; HH HT TH TT The probability of getting exactly one tail is 1/2 or 50%.
the probability is 0.03125 or 3.123%

The probability of tossing two heads in two coins is 0.25.

2 out of 8
The probability that exactly one will land heads up is 0.15625
The conditional probability is 1/4.
It is (1/2)3 = 1/8
Assuming it is a fair coin, the probability is 1/24 = 1/16.
