Question

A balloon vendor has 2 red, 3 blue and 4 green balloons. He wants to choose one of

them at random to give it to Pranali. Whet is the probability of the event thet

Pranali gets.

(1) a red ballons (2) a blue balloons.​

Answer 1

Answer :-

The probability that Pranali gets

1.) a red balloon = $\dfrac{2}{9}$.

2.) a blue ballon = $\dfrac{1}{3}$.

Given :

• Total number of red balloons = 2

• Total number of blue balloons = 3

• Total number of green balloons = 4

To find :-

The probability of the event that Pranali gets.

(1) a red ballon

(2) a blue balloon

Formula used :-

‣ Probability of an event

$= \frac{Number \: \: of \: \: favourable \: \: outcomes}{Total \: \: number \: \: of \: \: possible \: \: outcomes}$

Solution :-

We will use the formula of finding probability of an event to find the answer to the question.

➝ Total number of possible outcomes

= Total number of red balloons + Total number of blue balloons + Total number of green balloons

= 2 + 3 + 4

= 9

1.) Number of favourable outcomes = Total number of red balloons = 2

Probability of getting a red balloon = $\dfrac{2}{9}$

➛ The probability that Pranali gets a red balloon is $\dfrac{2}{9}$.

2.) Number of favourable outcomes = Total number of blue balloons = 3

Probability of getting a blue balloon = $\dfrac{3}{9} = \dfrac{1}{3}$

➛ The probability that Pranali gets a blue balloon is $\dfrac{1}{3}$.
