Question

A bag has five red stones two green three blue six yellow and four purple stones what is the probability of choosing a yellow stone from the back without looking?

Answer 1

Answer:

Probability of picking yellow stones from the bag is 0.3.

Step-by-step explanation:

Given:

Number of red stone in bag = 5

Number of green stone in bag = 2

Number of blue stone in bag = 3

Number of yellow stone in bag = 6

Number of purple stone in bag = 4

We need to find the probability of choosing yellow stone from the bag.

Solution:

First we will find the Total number of stones in the bag.

Total number of stones in the bag is equal to sum of Number of red stone in bag ,Number of green stone in bag, Number of blue stone in bag, Number of yellow stone in bag and Number of purple stone in bag.

framing in equation form we get;

Total number of stones in the bag = $5+2+3+6+4 =20$

Now Probability of picking yellow stones from the bag  can be calculated by  dividing Number of yellow stone in bag by Total number of stones in the bag.

framing in equation form we get;

$P(Y) =\frac{6}{20}= 0.3$

Hence Probability of picking yellow stones from the bag is 0.3.
