What is the probability of getting 2 red balls in a draw of two balls from a box containing 4 white and 3 red balls?
= 1/7.
What is the probability of getting 2 different Colours?
The probability of taking two balls of different colors is P(15/56). Probability of first ball taken being G(3/8) and R(5/7) for second ball taken.
What is the probability of exactly 1 red?
Therefore the probability of getting exactly one red ball is 99/190.
What is the minimum number of balls we have to choose to ensure we get 2 balls of the same color?
A minimum of 5 balls must be extracted to be sure we have extracted at least two balls with the same color.
