Question 14.
\nWhat is the probability of getting a marble which is not red from a bag containing 3 black, 8 yellow, 2 red and 5 white marbles?
\nSolution:
\nTotal number of balls = 3 black + 8 yellow + 2 red + 5 white = 18
\nn( S) = 18
\nNumber of the balls which are not red = 3 + 8 + 5 = 16
\nn(E) = 16
\nProbability = \\(\\frac { n(E) }{ n(S) }\\) = \\(\\frac { 16 }{ 18 }\\) = \\(\\frac { 8 }{ 9 }\\)<\/p>\n

Question 15.
\nFrom a well shuffled deck of 52 playing cards, a card is selected at random. Find the probability of getting
\n(i) a black card
\n(ii) a black king
\n(iii) an ace
\n(iv) a card of diamond
\nSolution:
\nHere, n(S) = 52
\n(i) Total number of black card = 26
\nn(E) = 26
\nProbability of getting a black card = \\(\\frac { n(E) }{ n(S) }\\) = \\(\\frac { 26 }{ 52 }\\) = \\(\\frac { 1 }{ 2 }\\)
\n(ii) Number of black king = 2
\nn(E) = 2
\nProbability of getting a black king = \\(\\frac { n(E) }{ n(S) }\\) = \\(\\frac { 2 }{ 52 }\\) = \\(\\frac { 1 }{ 26 }\\)
\n(iii) Number of aces = 4
\nn(E) = 4
\nProbability of getting an ace = \\(\\frac { n(E) }{ n(S) }\\) = \\(\\frac { 4 }{ 52 }\\) = \\(\\frac { 1 }{ 13 }\\)
\n(iv) Number of diamond cards = 13
\nn(E) = 13
\nProbability of getting a card of diamond = \\(\\frac { n(E) }{ n(S) }\\) = \\(\\frac { 13 }{ 52 }\\) = \\(\\frac { 1 }{ 4 }\\)<\/p>\n
