Math Probability for Grade 4

Math probability for grade 4 Introduction:

The grade 4 math probability is number of possible events are divided into total number of possible events this is called the math probability for grade 4. This grade 4 math probability is contains two types of distributions. That is the discrete and continuous distribution.  The general formation of the math probability for grade 4.

The probability of Event P (A) =` ("No. of possible events n(a)")/("Total no. of events n(s)")`

Math probability for grade 4 Examples:


Dice Problems:

Math probability for grade 4 Example 1:

Throw a single dice; what is the probability of getting number 1?

Solution:

Total Number of possible = n (s) = {1, 2, 3, 4, 5, 6}

Total Number of possibles = n (s) = 6

The number of outcomes = n (a) = {6}

The possible outcomes = n (a) = 1

The probability of getting value = `1/6.`

Math probability for grade 4 Example 2:

Throw a single dice; what is the probability of getting number 4?

Solution:

Total Number of possible = n (a) = {1, 2, 3, 4, 5, 6}

Total Number of possibles = n (s) = 6

The number of outcomes n (a) = {4}

The Number of possible outcomes = n (a) = 1

The probability of getting value =` 1/6.`

Having problem with Math Probability Problems keep reading my upcoming posts, i will try to help you.

Coins probability problems for grade 4:


Math probability for grade 4 Example 3:

Flip a coin and what is the probability of getting chance of one tail?

Solution:

Step 1:

Total number of outcomes = n (s) = {H, T} = 2

Step 2:

Tossing a coin with only one tail:

Number of possible event = n (a) = {T} = 1

Step 3:

Formula:

P (A) = n (a)/n (s)

Answer:

P (A) = `1/2.`

Convert into a decimal 0.5

The probability of one tail is 0.5 or Rounded 50%.

Math probability for grade 4 Example 4:

If throw a coin what is the probability of getting one head? The possible outcomes are:

Solution:

Step 1:

Total Number of Possible Events = n (s) = {T, H} = 2

Step 2:

Tossing a coin with only one head:

Number of possible events = n (a) = {H} = 1

Step 3:

Formula:

P (A) = n (a) / n (s)

Answer:

P (A) = `1/2` .

Convert into a decimal 0.5

The probability of one head is 0.5 or Rounded 50%.
