Kali Krause · Answer 1

1/2

Step-by-step explanation:

The coin is balanced, so if we call p the probability of heads, then p must be equal to 1-p, the probability of tails. Since p = 1-p, then 2p = 1, therefore p = 1/2. As a consecuence, there is a probability of 1/2 that the number of heads obtained is 1, and a probability of 1/2 that the number of heads obtained is 0.

I hope this works for you!
