Given:

A coin is flipped to decide which team starts the game. 

To do:

We have to find the probability that our team will start.

Solution:

A coin has two possible outcomes Head {H} and Tail {T}.

Hence, the total number of outcomes will be 2.

So, $n(S)=2$

As the Probability of getting a head or tail is equal, hence, number of successful outcomes: $n(E)=1$

We know that,

Probability $=\frac{ \text { Number of successful outcomes }}{ \text { Total number of outcomes }}$

Therefore, P(Team starts first) $=\frac{n(E)}{n(S)}$

$=\frac{1}{2}$

Thus, the probability that a team will start first is $\frac{1}{2}$.
