Check out the examples provided below to solve bag and marbles probability questions. You can solve the questions using Bag and Marbles Calculator.
(i) red ? (ii) white ? (iii) not green?
Solution:
Given,
A box contains 5 red marbles, 8 white marbles and 4 green marbles.
Probability = number of possible outcomes/total number of favorable outcomes
P(E) + P(not E) = 1
Total number of balls = 5 + 8 + 4 = 17
Probability of drawing red ball = 5/17
Probability of drawing white ball = 8/17
Probability of drawing green ball = 4/17
Let the probability of not getting a green ball be P (not E)
P (not E) = 1 - P (E)
= 1 - 4/17
= 13/17
Solution:
Probability = number of possible outcomes/total number of favorable outcomes
P(R) + P(not R) = 1
Number of red balls in a bag = 3
Number of black balls in a bag = 5
Total number of balls = 3 + 5 = 8
The probability that the ball drawn is red, P(R) = 3/8
The probability that the ball drawn is not red, P(not R) = 5/8
Solution:
Given,
Number of green marbles in a bag = 3
Number of blue marbles in a bag = 4
Number of orange marbles in a bag = 2
Total number of marbles = 9
The probability of picking orange marble = 2/9
The probability of not picking orange marble = 1 - 2/9 = 7/9
Given,
A bag contains 4 red and 8 blue marbles.
Total = 4 + 8 = 12
The probability of drawing red = 4/12 = 1/3
So, the statement is true.
The three types of probability are
Given,
number of black marbles = 3
number of yellow marble = 8
number of red marble = 2
number of white marble = 5
Total = 3 + 8 + 2 + 5 = 18
Subtract 2 red marbles
18 - 2 = 16
So, the answer is 16/18 = 8/9
