a bag contains 10 marbles. four of them are red, three blue, two white, and one yellow. a marble is drawn at random. what is the probability that it is not white? be sure to reduce.

Answer

Explanation:

Step1: Calculate number of non - white marbles

Total marbles are 10, white marbles are 2. So non - white marbles = 10 - 2 = 8.

Step2: Calculate probability

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, favorable outcomes (non - white marbles) is 8 and total outcomes is 10. So probability = $\frac{8}{10}=\frac{4}{5}$.

Answer:

$\frac{4}{5}$
