Question

You choose a marble from the bag. What is the probability you will NOT choose blue?1/25/72/72

Answer 1

Given a sample and required to get the probability of a particular outcome, we make a couple of considerations including:

- Sample Space: The universal set

- Required Outcome

We can identify these variables as:

Sample space: total number of marbles = 7

Required outcome: Not blue = 7 - 2 = 5

Probability is given as:

`\begin{gathered} P=\text{ }\frac{\text{number of required outcome}}{Sample\text{ space}}=(5)/(7) \\ P=(5)/(7) \end{gathered}`
