Let's find the ratio of the values of a 50 p.coin, a rupee coin, and a three Rupees Coin.

find the ratio of the values of a 50 p coin, a rupee coin, and a two rupee coin.

In each of the following experiments specify appropriate sample space A boy has 1 rupee coin, a 2 rupee coin and a 5 rupee coin in his pocket. He takes out two coins out of his pocket, one after the other.

There are coins of one rupee and 50 paisa in a box owned by elder brother of Mitali. The total value of the coins is Rs. 350. The sister of Mitali replaces (1)/(3) rd of the 50 paisa coins in the box by equal number of one rupee coins , so that the total value of the coins now becomes RS.400 . Determine the number of one rupee coins and 50 paisa coins each.

A bag contains 10 rupee - coins, 7 fifty-paise coins and 4 twenty finve-paise coins. Fine the probability of drawing (i) a rupee-coin (ii) three rupee-coins and (iii) three coins, one of each type, in the random drawing of three coins from the bag.

A box contains two 50 paise coins, five 25 paise coins and a certain fixed number N(geq2) of 10 and 5-paise coins. Five coins are taken out of the box at random. Find the probability that the total value of these 5 coins is less than 1 rupee and 50 paise.

The total number of ways in which a beggar can be given at least one rupee from four 25- paise coins, three 50-paisa coins and 2 one-rupee coins, is

One hundred identical coins, each with probability 'p' of showing heads are tossed once. If 0 lt p lt 1 and the probability of heads showing on 50 coins is equal to that of heads showing on 51 coins, then the value of p is

A person is permitted to selected at least one and at most n coins from a collection of (2n+1) distinct coins. If the total number of ways in which he can select coins is 255, find the value of ndot
