In a simultaneous throw of a pair of dice, find the probability of getting a sum, which is a perfect square. |
|
Answer» The experiment is throw a pair of dice. Therefore, the sample space is \(S=\begin{Bmatrix}(1,1), (1, 2),{(1,3)},(1,4),(1,5),(1,6)\\(2,1),{(2,2)},(2,3),(2,4),(2,5),(2,6)\\{(3,1)}, (3,2),(3,3),(3,4),(3,5),(3,6)\\(4,1),(4,2),(4,3),(4,4),(4,5),(4,6)\\(5,1),(5,2),(5,3),(5,4),(5,5),(5,6)\\(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)\end{Bmatrix}\) Total possible outcomes = n(S) = 6 \(\times\) 6 = 36. Let E = Event of getting the sum as a perfect square. Therefore, E = {(1, 3), (2, 2), (3, 1), (3, 6), (4, 5), (5, 4), (6, 3)} Number of favorable outcomes to event E = n(E) = 7 Thus, probability of getting the sum as a perfect square is p(E) = \(\frac{n(E)}{n(S)}=\frac{7}{36}\) |

Quick Ratio of a company is 1 : 1. State giving reasons (for any four), which of the following would improve, reduce or not change the ratio? (i) Purchase of machinery for cash (ii) Purchase of goods on credit (iii) Sale of furniture at cost (iv) Sale of goods at a profit (v) Redemption of debentures at a premium |
|
Answer» (i) Purchase of machinery for cash will reduce the total of Quick, Assets but total current liabilities will remain unchanged. Therefore, Quick Ratio will reduce. (ii) Purchase of goods on credit will increase total of current liabilities but total Quick Assets will remain unchanged. Therefore, Quick Ratio will reduce. (iii) Sale of furniture at cost will increase the total of Quick Assets. Therefore, Quick Ratio will improve. (iv) Sale of goods at profit will increase the total of Quick Assets. Therefore, Quick Ratio will improve. (v) Quick Ratio will not change since Quick Assets and Current Liabilities (because as per Schedule III redeemable debentures are Current Liabilities) both will reduce with the amount paid. |

Answer» Right choice is (a) Reversible inhibitors To elaborate: Irreversible inhibitors are those that bind very tightly to an enzyme, often by forming a covalent bond to one of its amino acid residues. Reversible inhibitors bind loosely to an enzyme and thus are readily displaced. Competitive inhibitors are reversible inhibitors of enzyme that compete with a substrate for access to the active site of the enzyme. |
