Question

q 26.) michelle has a box of markers. in the box there are 4 black markers, 2 red markers, 1 green marker, 1 blue marker, 1 purple marker, and 1 orange marker. if michelle reaches into the box and pulls out a marker, what is the probability that it will not be orange or red?

Explanation:

Step1: Calculate total number of markers

There are 4 black + 2 red+ 1 green + 1 blue + 1 purple + 1 orange = 10 markers.

Step2: Calculate number of non - orange and non - red markers

Non - orange and non - red markers are 4 black+ 1 green + 1 blue + 1 purple= 7 markers.

Step3: Calculate the probability

The probability $P$ of an event is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So the probability that the marker is not orange or red is $\frac{7}{10}$.

Answer:

$\frac{7}{10}$
