How to do probability problems

Probability Word Problems
Today let me help you on how to do probability problems. Probabilities is the chance of the outcome of an events of a particular experiment. Probabilities are occur always numbers between 0 (impossible) and 1(possible). The set of all possible outcome of a particular experiment is called as sample space. For example probabilitys of getting a 2 when rolling a dice is 1/6. In this lesson we shall discuss about how to solve the probability word problems.

How to Solve Probability Word Problems – Practice Problems
Solve these practice probability word problems.
Pr:1 In a jar there are 20 chocolates, 10 of which are white chocolate, 10 are milk chocolates. Find the probability of: This could also help us on logarithmic properties
a) White chocolate drawing first.
b) Milk chocolate drawing second.
Pr:2 A jar contains 4 orange candies, 5 lemon candies. If two candie are drawn at random, find the probability that 1 is lemon candy and 1 is orange candy.
Answer: 1) a) 1/2 , b) 1/19 2) 5/324
