A jar contains 10 red marbles numbered 1 to 10 and 10 blue marbles numbered 1 to 10.

A jar contains 10 red marbles. A the marble is red b the marble is odd numbered c the marble is red or odd numbered d the marble is blue and even numbered. If you remove marbles one at a time randomly what is the minimum number that must be removed to be certain that you have at least 2 marbles of each colour. A if one marble is drawn at random what is the probability that it is red. Two marbles are drawn without replacement.

10 x number of green marbles remains 30 hence total number of marbles becomes. There are 25 possible outcomes p red 10 25 2 5 b if two marbles are drawn randomly what is the probability that the first is red and the second blue if the first marble is replaced in. There are 10 ways to succeed. Calculating the probability of obtaining a red marble.
