Question

a bag contains 10 marbles. 2 of them are green. if one is randomly drawn, what is the probability that it is green? p(green)=?

Explanation:

Step1: Identify favorable outcomes

Number of green marbles = 2

Step2: Identify total outcomes

Total marbles = 10

Step3: Calculate probability

Probability = favorable/total = $\frac{2}{10}$ = $\frac{1}{5}$

Answer:

$\frac{1}{5}$
