A coin is flipped twice. What is the probability that it will come up once heads and once tails

Mathematics

1/2 or 50%, because there are two possibilities out of four.

If you think about flipping a coin twice, there are exactly four possible outcomes:

  Flip 1          Flip 2

1. tails            heads

2. tails            tails

3. heads        tails

4. heads        heads

In two of these possibilities (1 and 3) the coin flipped different sides.

That means 2/4 possibilities matched, and this can be reduced to 1/2

vovangra [49]
Answer: Linear

Explanation: A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
