Introduction to Probability:
Numerical measure of the likelihood of an event to occur is called as Probability. The probability should be a range in between 0 and 1.For solving probability practice problems we must know the following formula,
Probability of an event = number of times an event occurs / total number of outcomes
Consider an observation with 'n' possible ways and out of them in 'm' ways if the event 'A' occurs,then the probability of occurrence of the event 'A' is given by P(A) = m/n.
Let us workout some practice problems on solving probability in the following sections.
I like to share this Probability Problems and Solutions with you all through my article.
Probability on a coin problem:
Here Tossing a coin is a random experiment. When you toss a coin, you may get head or tail.Let us see how to solving the coin problem.
1: What is the probability of getting Head when you toss a coin?
We can have 2 out-comes for tossing a coin : Head or tail.
Here the event is getting Head. So we have 1 head.
So probability of getting head is one out of two outcomes.
Probability of getting Head = number of head event occurs / total number of outcomes
= 1/2
= 0.5
So the probability of this practice problem is 0.5
Probability on Card problem:
In 52 cards, there are 13 spades, 13 clovers, 13 diamonds and 13 hearts , 26 cards are red in color (diamonds and heart) and 26 are black (spade and clover).Let us see how to solving the card problems.
(1) What is the probability that you get a red card?
The event is getting a red card. There are 26 red cards.
Total sample spaces are 52(52 cards).
Probability of getting a red cards = number of red cards / sample space
= 26/52
=1/2
= 0.5
(2) What is the probability of getting a spade when you draw from a well shuffled pack of 52 cards?
Number of Spade cards = 13
Total Sample space = 52
Probability of getting a spade card = number of spade / total sample space
= 13/52
= 1/4
= 0.25
(3) What is the probability of getting a black queen in a pack of 52 cards?
In a pack of 52 cards, there are 2 Black Queens (spade 1, clover 1)
Total Sample space = 52
Probability of getting a black queen = number of black queen / total sample space
= 2/52
= 1/26
= 0.04
I have recently faced lot of problem while learning Fraction Simplifier, But thank to online resources of math which helped me to learn myself easily on net.
Practice Problem:
The following practice problems on solving probability will helps for good understanding.
Practice problem 1: What is the probability of getting Tail when you toss a coin?
Practice problem 2: What is the probability of getting a diamond when you draw from a well shuffled pack of
52 cards ?
Answer key:
Practice problem 1: 0.5
Practice problem 2: 0.25

The event is getting a red card. There are 26 red cards.
Total sample spaces are 52(52 cards).
Probability of getting a red cards = number of red cards / sample space
= 26/52
=1/2
= 0.5
(2) What is the probability of getting a spade when you draw from a well shuffled pack of 52 cards?
Number of Spade cards = 13
Total Sample space = 52
Probability of getting a spade card = number of spade / total sample space
= 13/52
= 1/4
= 0.25
(3) What is the probability of getting a black queen in a pack of 52 cards?
In a pack of 52 cards, there are 2 Black Queens (spade 1, clover 1)
