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 red? be sure to reduce.

Answer

Explanation:

Step1: Find number of non - red marbles

There are 3 blue, 2 white and 1 yellow marbles. So, $3 + 2+1=6$ non - red marbles.

Step2: Calculate probability

The probability $P$ of an event is given by $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Total number of marbles is 10. So, $P = \frac{6}{10}$.

Step3: Simplify the fraction

$\frac{6}{10}=\frac{3}{5}$ by dividing both numerator and denominator by 2.

Answer:

$\frac{3}{5}$
