Suppose the probability of being picked first in your class is 0.05. The odds of being picked first expressed in form of a: b is 1 : 19.
A probability is a number that represents the possibility or chance that a specific event will occur.
[tex]{\mathbf{\text{The probability of an event} = \dfrac{\text{number of desired outcome}}{\text{total number of possible outcome}}}[/tex]
From the given information;
∴
The odds of being picked first can be computed as:
[tex]\mathbf{=\dfrac{0.05}{1-0.05}}[/tex]
[tex]\mathbf{=\dfrac{0.05}{0.95}}[/tex]
[tex]\mathbf{\dfrac{1}{19}}[/tex]
= 1 : 19
Therefore, the odds of being picked first in terms of a: b is 1 : 19
