Total balls initially equal 9, reducing to 8 on the second draw without replacement. (i) P(Red then Blue) = (4/9) x (5/8) = 20/72 = 5/18. (ii) P(2 Blue) = (5/9) x (4/8) = 20/72 = 5/18.
Sample space has 8 numbers {1, 2, 3, 4, 5, 6, 7, 8}. The probabilities are: (i) P(8) = 1/8, (ii) P(odd) = 4/8 = 1/2, (iii) P(>2) = 6/8 = 3/4, (iv) P(<9) = 8/8 = 1, (v) P(multiple ...
The word PEACE has 5 letters: P, E, A, C, E. (i) Letters P, E, C occur 4 times, giving probability 4 / 5 = 0.8. (ii) Non-E letters are P, A, C (3 letters), giving probability 3 / 5 ...
Total tyres recorded equal 1000. The required probabilities are: (i) 20 / 1000 = 0.02, (ii) (210 + 325) / 1000 = 535 / 1000 = 0.535 and (iii) 445 / 1000 = 0.445.
