If the number to the right of the decimal point is 75 or above, then we add 1 to the left side of the decimal point and make the right side 0. Here, we observe that, 5 students have scored marks below 10, i.e. Total number of bulbs, n (S) = 24. Find the unknown entries o, b, c, d, e and f in the following distribution of heights of students in a class Two dice are thrown simultaneously. The first few multiples of 5 are 5, 10, 15, 20, 25, 30, and so on.
