The value of PI upto 50 decimal places is given below : : What are the most and the least frequency occurring digits ?

On one page of a telephone directory, there were 200 telephone numbers. The frequency distribution of their unit place digit (for example, in the number 25828573, the unit place digit is 3) is given in Table 15.7 : Without looking at the page, the pencil is placed on one of these numbers, i.e., the number is chosen at random. What is the probability that the digit in its unit place is 6?

From a telephone directory, 200 telephone numbers are chosen and frequency distribution of their right most digits (For example in the number 28563, the rightmost digit is 3) is given as follows : A next number is selected. What will be the probability that the rightmost digit in the number is 6.

If 4-digit numbers greater than 5,000 are randomly formed from the digits 0, 1,3, 5, and 7, what is the probability of forming a number divisible by 5 when, (i) the digits are repeated? (ii)the repetition of digits is not allowed?

If 4-digit numbers greater than 5000 are randomly formed from the digits 0, 1, 3, 5 and 7 what is the probability of forming a number divisible by 5 when, i) the digits are repeated ? ii) the repetition of digits is not allowed ?

The pH values of some substances are given below:(i)Apples: 5.0-6.5(ii) Onion: 6.0-7.0(iii)Mint: 7.0-8.0 Which of these are most (i) acidic (ii)basic?

Suppose U denotes the number of digits in the number (60)^(100) and M denotes the number of cyphers after decimal, before a significant figure comes in (8)^(-296) . If the fraction U/M is expressed as rational number in the lowest term as p//q (given log_(10)2=0.301 and log_(10)3=0.477 ) . The value of p is
