Question 1 Exercise 3.4

Q3) A coin is flipped to decide which team starts the game. What is the probability that your team will start?

Answer:

Solution:

Sample space of a coin = H, T

n(s) = 2

Number if successful event = 1

n(e) = 1

PRobability = \frac{Number\ of\ favourable\ outcomes}{Total\ number\ of\ outcomes}

= \frac{1}{2}

"hi friends welcome to lido homework
so today we are going to solve this
interesting question
so the question says that a coin was
flipped to decide which steam starts the
game
so what is the probability that your
team will start the game
so basically a coin have two faces
okay so one is head
and one is tail okay
so now one team can either choose head
or tail so what is the pro probability
that your team starts first so for
example let us think we started with
head so our selection is head okay
so the probability of our team to start
the
game is the number of favorable outcomes
so we will win the game
that means we will start the game when
the toss
the flipped coin shows hit right so that
is
one by what are the total number of
outcomes either head can come
or tail can come so there are two
possible outcomes so the probability
that we will start a game
is one by two similarly if you select
tail also that means the opposite team
let us just find for the opposite team
also
so the probability for the opposite team
is if you select
tail that means the opposite team
selected t
so the tail can come and what are the
total number of events that is
two so the probability of the other
team to start the game is one by two
so both of your team has equal
probabilities to start the game
okay so that's for this video if you
