Question

A bowl contains 10 red marbles, 20 yellow marbles and 20 blue marbles. The probability of picking a yellow marble is

Answer 1

Answer:

the probability of picking a yellow marble is 2/5.

Answer 2

$\huge\boxed{\sf\purple{Given :-}}$

• Red marbles - 10
• Yellow marbles - 20
• Blue marbles - 20

$\huge\boxed{\sf\orange{ To\: find :-}}$

The probability of picking a yellow marble.

$\huge\boxed{\sf{Formula :- }}$

Probability = $\sf\pink{ \frac{favourable \:outcome}{total \:number \:of \:outcomes}}$

So , putting up the formula let's find the answer for the given question.

Total number of outcomes :

10 + 20 + 20 = 50

Number of favourable outcomes:

20

Number of Favourable outcomes means the number of possible outcomes that we want.

Here there are 20 yellow marbles ; and we want to the probability of picking a yellow marble.

Hence we will take 20 which is the total number of yellow marbles.

Putting up the formula :

$\longrightarrow{\sf\pink{ \frac{20}{50}}}$

$\implies{\sf\pink{\frac{2}{5}}}$

Hence the probability of getting a yellow marble is :

$\huge{\sf\green{\frac{2}{5}}}$
