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.

Two coin (a one rupee coin and a two rupee coin) are tossed once. Find a sample space.

Write the sample space in each of the following : An unbiased coin is tossed one time.

Write the sample space in each of the following : An unbiased coin is tossed two times.

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.

If E be the random experiment of throwing an unbiased coin and S be its sample space and if H and T denotes the events of occurrence of head and tail respectively, then If two coins are thrown simultaneously or one coin is thrown two times, then find the sample space of E.

Which of the following arguments are correct and which are not correct? Give reasons. i) If two coins are tossed simultaneously there are three possible outcomes - two heads, two tails or one of each. Therefore, for each of these outcomes, the probability is 1/3 ii)If a die is thrown, there are two possible outcomes - an odd number or an even number. Therefore, the probability of getting an odd number is 1/2

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.

Write down the sample spaces in each of the folloing random experiments: Experiment of tossing two balaned coins
