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.

You are given four sources of light each one providing a light of single colour - red, blue, green and yellow, Suppose the angle of refraction for a beam of yellow light corresponding to a particular angle of incidence at the interface of two media is 90^(@) . Which of the following statement is correct if the source of yellow light is replaced with other lights without changing the angle of incidence?

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

An urn contains 3 red balls and n white balls. Mr. A draws two balls together from the urn. The probability that they have the same color is 1/2 Mr. B. Draws one balls form the urn, notes its color and replaces it. He then draws a second ball from the urn and finds that both balls have the same color is 5/8. The possible value of n is (a) 9 b. 6 c. 5 d. 1

A bag contains five green marbles, three blue marbles, two red marbles, and two yellow marbles. One marble is drawn out randomly. a) Are the four different colour outcomes equally likely? Explain. b) Find the probability of drawing each colour marble i.e. , P(green), P(blue), P(red) and P(yellow) c) Find the sum of their probabilities.

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

An urn contains nine balls of which three are red, four are blue and two are green. Three balls are drawn at random without replacement from the urn. The probability that the three balls have different colour is

A box contains 2 white balls, 3 black balls & 4 red balls. In how many ways can three balls be drawn from the box if atleast one black ball is to be included in draw (the balls of the same colour are different).
