Question

A bag contains 3 red balls, 3 blue balls, and 9 green balls. Ashish draws 2 balls out of the bag. What is the probability that he gets a green ball and a red ball?​

Answer 1

Answer:

Given-

• Red balls = 3
• Blue balls = 3
• Green balls = 9
• Total balls = 15

To find:

• Probability of getting a green and red ball.

Solution :

We know that,

Probability = Favourable outcomes/Total outcomes

Here, favourable outcomes = green and red ball ( 3 + 9 = 12 )

Total outcomes = 15

→ Probability = 12/15 => 4/5

Hence, probability will be 4/5.

Answer 2

$\large\mathcal\purple{\underbrace{QUESTION:-}}$

A bag contains 3 red balls, 3 blue balls, and 9 green balls. Ashish draws 2 balls out of the bag. What is the probability that he gets a green ball and a red ball?

$\large\mathcal\red{\underbrace{SOLUTION:-}}$

• Red balls = 3.
• Blue balls = 3.
• Green balls = 9.

Formula Of Probability :-

Favourable Outcomes/Total Outcomes.

• Favourable Outcomes = 9+3 = 12 balls.
• Total Outcomes = 15

⇢ 12/15

⇢ 4/5.

Hence, Probability = 4/5.
