$\LARGE{ \underline{\underline{ \orange{ \bf{Required \: answer:}}}}}$

Given:

Red marbles = 4

Yellow marbles = 8

To Find:

Probability of

a) picking a yellow marble.

b) picking a red marble.

Formula:

Since we have 4 red marbles and 8 yellow marbles, to find the probability we have to divide the number of marbles in the question asked and the total number of marbles.

Solution:

a) Probability of picking a yellow marble:

No. of yellow marbles = 8

Total no. of marbles = 12

Let's find the probability:

8/12

4/6

2/3

b) Probability of picking a red marble:

No. of red marbles = 4

Total no. of marbles = 12

Let's find the probability:

4/12

2/6

1/3

Hence,

Probability of picking a yellow marble is 2/3

Probability of picking a red marble is 1/3
