Question

there are 3 red, 2 yellow, 1 blue, and 5 green deflated balloons in a sack. what is the probability of drawing out a yellow balloon?
o $\frac{3}{11}$
o $\frac{1}{11}$
o $\frac{2}{11}$
o $\frac{5}{11}$

Explanation:

Step1: Calculate total balloons

$3 + 2+1 + 5=11$

Step2: Find probability of yellow

$\text{Probability}=\frac{\text{Number of yellow}}{\text{Total number}}=\frac{2}{11}$

Answer:

$\frac{2}{11}$ (the third option in the multiple - choice list)
