Question

1. a bag contains 4 yellow, 3 blue, and 3 orange marbles. what is the probability of not drawing orange?

3/10
4/10
1/2
7/10

Explanation:

Step1: Find total number of marbles

Total marbles = Yellow + Blue + Orange = \(4 + 3 + 3 = 10\)

Step2: Find number of non - orange marbles

Non - orange marbles = Yellow + Blue = \(4 + 3 = 7\)

Step3: Calculate probability of not drawing orange

Probability = \(\frac{\text{Number of non - orange marbles}}{\text{Total number of marbles}}=\frac{7}{10}\)

Answer:

7/10 (corresponding to the option with 7/10)
