Question

38 a bag contains 7 marbles, of which 1 is orange. what is the probability that a randomly selected marble will not be orange? answer: note: write your answer as a simplified fraction.

Explanation:

Step1: Find number of non - orange marbles

Total marbles = 7, orange marbles = 1. So non - orange marbles = 7 - 1 = 6.

Step2: Calculate probability

Probability of an event = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, favorable outcomes (non - orange) = 6, total outcomes = 7. So probability = $\frac{6}{7}$.

Answer:

$\frac{6}{7}$
