Explanation

When a dice is rolled, there are 6 possible outcomes: 1, 2, 3, 4, 5, and 6.

The numbers greater than 4 are 5 and 6, which are 2 outcomes.

So, the probability of getting a number greater than 4 is:

Probability = Number of favorable outcomes / Total number of outcomes

= 2/6

= 1/3

Explanation

Given A:B = 3:4 and B:C = 12:13.

First, make the ratios for B consistent:

A:B = 3:4 = 9:12 (multiplied by 3)

Now, B:C = 12:13

A:B:C = 9:12:13

A:C = 9:13

• Odd numbers are integers that are not divisible by 2.
• They can be expressed in the form 2n + 1, where n is any integer.
• This formula always produces odd values like 1, 3, 5, 7, etc.
