What is Probability?

Probability is known as the chance of some of the events to occur. When we need to know about the probability of a particular event which has to take place, we think of the chances that we expect in accordance with every possibility that can happen.


When you aren't sure about the result of a specific event, you'll specify the chances or how likely the result. Analyzing the events that are governed by probability is known as Statistics. Statistics Problems can be solved using math formulas.

A simple example that defines the basics of probability is flipping a coin.

We will get two possible outcomes when a coin is flipped, i.e,

Heads

Tails

What will be the probability for a fair coin (which has two different faces) that it lands on the Heads?

Since there are only two possible outcomes which will occur out of 1, hence the probability of the coin landing on Heads would be

P(H) = Heads / Tails + Heads = ½

Hence, P(H) = 0.5 or 50%

Here, we bring you the geometric probability worksheet pdf to assist you in improving within the probability concepts that also include applied mathematics, probability statistics along with applications of probability.


Probability Formula

The probability formula is defined because of the likelihood of an occasion to happen. It is equal to the ratio of the number of favorable results and the total number of outcomes. The formula for the probability of an occasion to occur is given by:

P(E) = Total Number of the favorable outcomes/Total Number of the outcomes


Probability Worksheet for Class 9

  • Two coins are tossed at the same time for 400 times and we get 2 heads which equals 180 times, one head = 148 times, and no head = 70 times. If two coins are tossed at random, what is the probability of getting 2 heads, 1 head and 0 heads.

  • According to the meteorological report for 300 consecutive days during a year, its weather outlook was correct 180 times. Out of those days, at some point was chosen randomly, what's the probability that the weather outlook was correct thereon day and not correct there on the day.

Probability is considered to be one of the easiest chapters in math. In addition, students find it fun to take out the probability of certain events. For example- flipping a coin to toss for your cricket match. 


However, it's important that you look at the topic from an examination point of view.  Upto class 8, students are taught the basic probability however in grade 9, they are introduced to the standard probability. For scoring well in these board classes, it's important that students practice their worksheets on a regular basis.

5. A survey of 200 students was conducted to check the opinion of students about the topic of geometry. It was found that 175 students do not like geometry. Find the probability of the students who like geometry.

Total no. of Students = 200

The no. of students who do not like geometry = 175

The no. of students who like geometry = 200-175=25

∴P (no. of students who like geometry) = 25

So, the probability is ¼ or 25%.
