Solution

\frac{1}{4}

étapes des solutions

The possible outcomes when a coin is thrown two times are

2 \cdot 2

Therefore, the number of possible outcomes:

2^{2}

Find the number of favorable outcomes of both coins land on heads:

1

Probability

= \frac{number of favorable outcomes}{total number of outcomes}

= \frac{1}{2 ^{2}}

2^{2} = 4

= \frac{1}{4}
