Question

You flip a coin.What is P(heads or tails)?Simplify your answer and write it as a fraction or whole number.

Answer 1

Given: You flip a coin.

The coin has a head and a tail

So, the total outcomes = 2

P(Head) = 1/2

P(Tail) = 1/2

As we know:

$P(A\text{ }or\text{ }B)=P(A)+P(B)$

So, P(heads or tails) = P(Head) + P(Tail) = 1/2 + 1/2 = 1

So, the answer will be 1
