Question

How do you solve probability problems $?$

Answer 1

To solve probability problem:

Probability is the possibility of an event to occur.

So,

Probability $=$$\frac{\mathrm{number}\mathrm{of}\mathrm{favourable}\mathrm{outcomes}}{\mathrm{total}\mathrm{number}\mathrm{of}\mathrm{outcomes}}$

That is, $\mathit{P}\mathbf{\left(}\mathit{E}\mathbf{\right)}\mathbf{}\mathbf{=}\mathbf{}\frac{\mathbf{n}\left(E\right)}{\mathbf{n}\left(S\right)}$

Hence, we can solve problems based on probability by the above stated formula .
