Question

17. when a particular die is rolled ,the probability of getting 6 is 1/3 . the probability of getting two, three, four, and five are each 1/6. On the basis of above information answer the following questions : i) The probability of getting one, is: (a) 1 (b) ½ (c) 0 (d) 1/6 ii) If the die is rolled twice the probability of getting the sum 6, is (A) 1 (B) 1/2 (C) 1/12 (D) 1/6 III) IF this die is rolled twice the probability of getting the sum 12 or less than 12 is : (A) 1 (B) 1/2 (C) 1/12 (D) 0 IV) IF the dice is rolled twice the probability of getting an od product is : (A) 1 (B) ½ (C) 1/12 (D) 1/9 V) if this die is rolled twice the probability of getting the product is 1, is : (A) 1 (B) 0 (C ) 1/2 (D) 1/3 18) a hall has dimensions 32m by 20m . part of the floor of the hall is covered with tiles , as shown by shaded rectangle black in the figure part of the floor not covered by the tiles has a uniform width of “x” m. On the basis of above information answer the following: (i) The expression in terms of x for the breadth of the floor covered by the tiles is : (A) 32- 2 x (B) 20- 2x (C) 32-x (D) 20-x (ii) In terms of x for the length of the floor covered by tiles is : (A) 20-2x (B) 20-x (C) 32- 2x (D) 32-x (III)GIVEN that the floor area covered by the tiles is 448 sq m what equation in term of x is formulated? (A) X^2 – 26X +48=0 (B) 2X^2 -13X+ 24=0 (C) X^2- 2X + 12=0 (D) 3X^2 -6X +16=0 (iv) what is the width of the floor not covered by the tiles? (A) 1.5M (B) 2 M (C) 2.5M (D) 3M (V)WHAT IS THE COST OF TILING AT THE RATE OF 28 RS PER SQ m? (A) RS 12544B) RS 13664 C) RS 11 648 D) RS 8064​
