(i) Outcome of getting a number 6 from ten separate slips is one. Therefore, probability of getting a number 6=1/10 (ii) Numbers less than 6 are 1, 2, 3, 4 and 5 which are five. So there are 5 outcomes. Therefore, probability of getting a number less than 6= 5/10 = 1/2 (iii) Number greater than 6 ouRead more
(i) Outcome of getting a number 6 from ten separate slips is one.
Therefore, probability of getting a number 6=1/10
(ii) Numbers less than 6 are 1, 2, 3, 4 and 5 which are five. So there are 5 outcomes.
Therefore, probability of getting a number less than 6= 5/10 = 1/2
(iii) Number greater than 6 out of ten that are 7, 8, 9, 10. So there are 4 possible
outcomes.
Therefore, probability of getting a number greater than 6 = 4/10 = 2/5
(iv) One digit numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9 out of ten.
Therefore, probability of getting a 1-digit number = 9/10

If you have a spinning wheel with 3 green sectors, 1 blue sector and 1 red sector, what is the probability of getting a green sector? What is the probability of getting a none-blue sector?
There are five sectors. Three sectors are green out of five sectors. Therefore, probability of getting a green sector = 3/5 There is one blue sector out of five sectors. Non-blue sectors = 5 – 1 = 4 sectors Therefore, probability of getting a non-blue sector = 4/5 Class 8 Maths Chapter 5 Exercise 5.Read more
