Probability Elementary Math

Introduction for probability elementary math:

Let us see probability elementary math for in this topic. The probability is the mathematics. This is used to find the expected value of the combination possibles. The probability is the number of possible outcomes is divided into the total number of outcomes.

Probability = `"Number of possible outcomes"/"Total number of possibles"`

Probability Elementary Math Examples:

Dice Problems:

Probability elementary math - Example 1:

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

Solution:

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

n(s) = 6

Number of possible events n (a) = {4}

n (a) = 1

Probability of getting number 4 = `1/6` (or) 0.1667

Probability elementary math - Example 2:

Throw a dice; find the probability of get number 2.

Solution:

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

n (s) = 6

The number of outcomes n (a) = {2}

n (a) = 1

Probability of getting number 2 = `1/6 ` (or) 0.1667

Probability elementary math - Example 3:

Throw a dice; what is the probability of get number 1.

Solution:

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

n (s) = 6

Number of Possible Events = n (a) = {1}

n (a) = 1

Probability of Getting Number 1 = `1/6` (or) 0.1667

Probability elementary math - Example 4:

Throw a dice; what is the probability of number 4.

Solution:

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

n (s) = 6

Number of Possible Events = n (a) = {4}

n (a) = 1

Probability of Getting Number 4 = `1/6 ` or 0.1667

Coins Problems:

Probability elementary math - Example 5:

To throw a coin and what is the probability of getting head?

Solution:

Step 1:

Possible outcomes are:

n (s) = {H, T} = 2

Step 2:

Tossing a coin with only one head:

n (a) = {H} = 1

Step 3:

Formula:

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

Answer:

P (A) = `1/2.`

Probability of getting head is 0.5 or Rounded 50%.

Probability elementary math - Example 6:

Let fly a coin and what is the probability of getting tail?

Solution:

Step 1:

Total Possible outcomes are:

n (s) = {H, T} = 2

Step 2:

Throwing a coin with tail:

n (a) = {T}=1

Step 3:

Formula for Finding Probability:

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

Answer:

P (A) = `1/2.`

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