# Find the sample space for tossing 2 coins, then find p(exactly 1 head).

Sample space, in probability, is referred to as the collection of all possible outcomes in any random experiment. It is denoted by "S".

## Answer: The sample space for tossing 2 coins is { TT, TH, HT, HH } and p(exactly 1 head) is 1/2.

Let's observe the experiment of tossing 2 coins.

**Explanation:**

Head(H), Tail(T) are two possible outcomes when we toss a coin.

So, the sample space when we toss 2 coins is { TT, TH, HT, HH }.

Total number of outcomes = 4

No.of favorable outcomes = N(exactly 1 head) = {TH, HT} = 2

Probability(exactly 1 head) = (No. of favorable outcomes) / (Total no. of outcomes)

= 2 / 4

= 1/2

### Thus, sample space is { TT, TH, HT, HH } and p(exactly 1 head) is 1/2.
