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 blue?
Answer
Answer:
$\frac{7}{10}$

$4 + 2+1=7$
Step2: Calculate probability
Probability = $\frac{\text{Number of non - blue marbles}}{\text{Total number of marbles}}=\frac{7}{10}$
