\nList the outcomes you can see in these experiments.
\n(i) Spinning a wheel
\n
\n(ii) Tossing two coins together
\nSolution:
\n(i) On spinning the wheel, we can get the following outcomes B, C, D, E and A.
\n(ii) When two coins are tossed together, we get the following outcomes
\nHH, HT, TH, TT (Where H denotes Head and T denotes Tail)<\/p>\n
\nWhen a die is thrown, list the outcomes of an event of getting
\n(i) (a) a prime number
\n(b) not a prime number
\n(ii) (a) a number greater than 5
\n(b) a number not greater than 5
\nSolution:
\n(i) (a) The prime number are 2, 3 and 5
\nRequired outcomes = 2, 3 and 5
\n(b) Outcomes for not a prime number are 1, 4 and 6
\nRequired outcomes = 1, 4, 6.
\n(ii) (a) Outcomes for a number greater than 5 = 6
\nRequired outcome = 6
\n(b) Outcomes for a number not greater than 5 are 1, 2, 3, 4, 5
\nRequired outcomes = 1, 2, 3, 4, 5.<\/p>\n
\nFind the
\n(i) Probability of the pointer stopping on D in (Question 1-(a))?
\n(ii) Probability of getting an ace from a well-shuffled deck of 52 playing cards?
\n(iii) Probability of getting a red apple, (see figure below)
\n
\nSolution:
\n(i) Refer to fig. Question 1-(a)
\nTotal number of sectors = 5
\nNumber of sector where the pointer stops = 1, i.e. D
\nProbability of pointer stopping at D = \\(\\frac { 1 }{ 5 }\\)
\n(ii) Number of aces = 4 (one from each suit i.e. heart, diamond, club and spade)
\nTotal number of playing cards = 52
\nProbability of getting an ace
\n
\n(iii) Total number of apples = 7
\nNumber of red apples = 4
\nProbability of getting red apples
\n<\/p>\n
\nNumbers 1 to 10 are written on ten separate slips (one number on one slip), kept in a box and mixed well. One slip is choosen from the box without looking into it. What is the probability of:
\n(i) getting a number 6?
\n(ii) getting a number less than 6?
\n(iii) getting a number greater than 6?
\n(iv) getting a 1-digit number?
\nSolution:
\n(i) Probability of getting a number 6 = \\(\\frac { 1 }{ 10 }\\)
\n(ii) Probability of getting a number less than 6 = \\(\\frac { 5 }{ 10 }\\) = \\(\\frac { 1 }{ 2 }\\) [\u2235 Numbers less than 6 are 1, 2, 3, 4, 5]
\n(iii) Probability of getting a number greater than 6 = \\(\\frac { 4 }{ 10 }\\) = \\(\\frac { 2 }{ 5 }\\) [\u2235 Number greater than 6 are 7, 8, 9, 10]
\n(iv) Probability of getting a 1-digit number = \\(\\frac { 9 }{ 10 }\\)
\n[\u2235 1-digit numbers are 9, i.e. 1, 2, 3, 4, 5, 6, 7, 8, 9]<\/p>\n
\nIf 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 non-blue sector?
\nSolution:
\nTotal number of sectors are = 3 green + 1 blue + 1 red = 5 sectors
\nProbability of getting a green sector
\n
\nNumber of non-blue sectors are = 3 green + 1 red = 4 sectors
\nProbability of getting non-blue sector
\n<\/p>\n
\nFind the probabilities of the events given in Question 2.
\nSolution:
\nRefer to Question 2, we have
\n(i) (a) Probability of getting a prime number
\n
\n(b) Probability of getting a non-prime number
\n
\n(ii) (a) Probability of getting a number greater than 5 = \\(\\frac { 1 }{ 6 }\\)
\n(b) Probability of a number not greater than 5 = \\(\\frac { 5}{ 6 }\\) or, 1 – \\(\\frac { 1 }{ 6 }\\) = \\(\\frac { 5 }{ 6 }\\)<\/p>\nMore CBSE Class 8 Study Material<\/h4>\n
