Based on a tree diagram of the possibilities when two coins are tossed, the theoretical probability that at least one coin is heads is B. 075.

What is the probability that one coin is heads?

If two coins are thrown, the possibilities would be:

  • Head - Head.
  • Head - Tail.
  • Tail - Head.
  • Tail - Tail.

There are therefore 4 possibilities and of these, heads will theoretically appear in 3.

Probability is therefore:
= 3 / 4

= 0.75
