You have a jar with five identical balls of different colours (White, Red, Blue, Grey and Yellow) and you have to pickup (draw) a ball without looking at it. List the possible outcomes you get.

there are two identical balls of same material one being solid and the other being hollow How will you distinguish them without weighting

A bag contains a red ball a blue ball and an yellow ball, all the balls being of the same size. Manasa takes out a ball from the bag without looking into it. What is the probability that she takes a (i) yellow ball? (ii) red ball? (iii) blue ball?

Suppose you have three resistor each of value (30 Omega) .List all the different resistances you can obtian using them.

Selecting a different colour ball from a bag of 5 red balls, 4 blue balls and 1 black ball. Winning in a game of carrom. Units place of a two digit number selected may be 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9. Selecting a different colour ball from a bag of 10 red balls, 10 blue balls and 10 black balls. Raining on a particular day of July

A few normal seedlings of tomato were a few days they were found to have become white coloured like albinis.Which of the following terms will you use to describe them?

Fifteen identical balls have to be put in five different boxes. Each box can contain any number of balls. The total number of ways of putting the balls into the boxes so that each box contains at least two balls is equal to a. .^9C_5 b. .^10 C_5 c. .^6C_5 d. .^10 C_6

Take three different colour sheets , place one over the other and draw a triangle on the top sheet. Cut the sheets to get triangles of different colour which are identical. Mark the vertices and the angles as shown. Place the interior angles angle1,angle2 and angle3 on a straight line, adjacent to each other, without leaving any gap. What can you say about the total measure of the three angles angle1,angle2 and angle3 ? Can you use the same figure to explain the ''Exterior angle property'' of a triangle ? If a side of a triangle is stretched, the exterior angle so formed is equal to the sum of the two remote interior angles.

You are holding a cage containing a bird. Do you have to make less effort if the bird flies from its position in the cage and manages to stay in the middle without touching the walls of he cage? Does it make a difference whether the cage is completely closed or it has rods to let air pass?
