RD Sharma Solutions Class 8 Mathematics Solutions for Data Handling Probability Exercise 26.1 in Chapter 26 - Data Handling Probability

Question 13 Data Handling Probability Exercise 26.1

A bag contains 5 red marbles, 8 white marbles, 4 green marbles. What is the probability that if one marble is taken out of the bag at random, it will be

(i) red

(ii) white

(iii)not green

(i) Red

Total numbers of red marbles = 5 Number of white marbles = 8 Number of green marbles = 4

Total number of marbles = 5 + 8 + 4 = 17

Probability of getting a red marble is = Total number of red marbles/Total number of marbles

= 5/17

∴ Probability of getting a red marble is 5/17

(ii) White

Total numbers of red marbles = 5 Number of white marbles = 8 Number of green marbles = 4

Total number of marbles = 5 + 8 + 4 = 17

P robability of getting a white marble is = Total number of white marbles/Total number of marbles

= 8/17

∴ Probability of getting a white marble is 8/17

(iii) Not green

Total numbers of red marbles = 5 Number of white marbles = 8 Number of green marbles = 4

Total number of marbles = 5 + 8 + 4 = 17

Total number of non-green marbles = 5 + 8 = 13

Probability of getting a non-green marble is = Total number of non-green marbles/Total number of marbles

= 13/17

∴ Probability of getting a non-green marble is 13/17
