Introduction to 4th grade math probability:
Generally probability is defined as the ratio of the number do ways of an event occur to the total number of possible outcomes, probability is used in the area of statistics, finance, gambling and science.
Probability formula for 4th grade math probability
The probability of event P (A) = no of possible events n (a) `//` the total number of the events n(s)
Example problem -4th grade math probability
Suppose a single die is rolled find the probability of getting odd number and also even number? ii) Probability of getting each number?
Solution:
Generally the die has 6 sides ,they are numbered as 1,2,3,4,5,6
From the six number we can tell the odd number as 1,3,5 and even number as 2,4,6
Here the possible outcomes of these experiments are 1, 2, and 3,4,5,6.
First we have to find the probability of getting odd number, the die as 3 odd numbers
So the probability p (odd) =3/6
Here 6 is the total number
Similarly the probability of even number will be written as
Probability p (even) =3/6
ii) Probability of getting each number it will be shown as below,
P (1) =1/6
P (2) =1/6
P (3) =1/6
P (4) =1/6
P (5) =1/6
P (6) =1/6
Example problem -4th grade math probability
Here the circle is divided into 8 equal parts and they are colored using the different color find the probability of choosing green color?
Solution:
It is divided into equal parts so the total number will be present in the denominator and counts the how many colors are shaded using green, here colors are shade in a green so it must be come in the numerator parts
Then the answer is 4/8
Example problem -4th grade math probability
A basket contains the fruits, it has 5 apples, 3 orange, 11 mango and 1plum what is the probability of choosing mango without looking the basket?
Solution:
The total number of fruits is 5 apples, 3 orange, 11 mango and 1plum so the total number of fruits in the basket is 5+3+11+1=20
P (mango) =11/20
Here numerator represents the count of apple and denominator represents the total count of fruits
