A bag has 3 red marbles, 2 blue and 4 yellow. What is the theoretical probability of pulling a red?
1/3
3/10
1/6
1/9
Answers
Given - Number of red, blue and yellow marbles
Find - Probability of pulling red marble
Solution - The theoretical probability of pulling a red marble is 1/3.
The formula to calculate the probability is = number of favourable outcomes/total number of outcomes.
The number of favourable outcomes is the number of red marbles.
The total number of outcomes is the total number of marbles.
Total number of marbles = 3 + 2 + 4
Total number of marbles = 9
Keep the values in the formula to find the probability.
Probability = 3/9
Probability = 1/3
Thus, the theoretical probability of pulling a red marble is 1/3.
Answer:
Theoretical probability of pulling a red marvels is 3/9 = 1/3.
Step-by-step explanation:
A bag has 3 red marbles, 2 blue marbles and 4 yellow marbles .
Total no. of balls = 3 + 2 + 4 = 9 .
Theoritical probability means ( no. of chances / total sample space).
Here ,
Theoretical probability of pulling a red marvels is 3/9 = 1/3.
Theoretical probability of pulling a blue marvels is 2/9.
Theoretical probability of pulling a yellow marvels is 4/9.
So , theoretical probability of pulling a red marvels is 3/9 = 1/3.
