Magenta is obtained by mixing red and blue.

An artist makes a certain shade of green paint by mixing blue and yellow inn a ratio of 3:4. She makes orange by mixing red and yellow in the ratio of 2:3. If on one day she mixes both green and orange and uses equal amounts of blue and red paint, what fractional part of the paint that she uses is yellow?

Joe reaches into a bag containing 5 red, 4 blue, and 8 orange jellybeans, and randomly selects three jellybeans. {:("Quantity A","Quantity B"),("The probability of selecting a","The probability of selecting a"),("red, then a blue, then an","red, then another red, then an"),("oragne jellybean","orange jellybean"):}

An acidic buffer is obtained on mixing :

A diffraction pattern is obtained using a beam of redlight. What happens if the red light is replaced by blue light

A diffraction pattern is obtained using a beam of redlight. What happens if the red light is replaced by blue light

A mixture is made by combining a red liquid and a blue liquid so that the ratio of the red liquid to the blue liquid is 17 to 3 by weight. How many liters of the blue liquid are needed to make a 420 - liter mixture?

In how many ways can 5 colours be selected out of 8 different colours including red, blue, and green : a) if blue and green are always to be included (b) if red is always excluded. (c) if red and blue are included but green excluded.

A box contains 3 red and 5 blue balls. Two balls are drawn one by one at as time at random without replacement. Find the probability of getting 1 red and 1 blue ball.

The refractive index of a glass is 1.520 for red light and 1.525 for blue light. Let D_1 and D_2 be angles of minimum deviation for red and blue light respectively in a prism of this glass. Then,

A bag contains 6 red and 5 blue balls and another bag contains 5 red and 8 blue balls. A ball is drawn from the first bag and without noticing its colour is put in the second bag. A ball is then drawn from the second bag. Find the probability that the ball drawn is blue in colour.
