Respuesta :

The formula for determining probability is expressed as

Probability = number of favorable outcomes/number of total outcomes

number of favorable outcomes = number of blue socks = 2

number of total outcomes = number of all socks = 3 + 4 + 2 + 4 = 13

Thus, the probability of picking a blue sock is

2/13 = 0.1538

Converting to percentage, we would multiply by 100. We have

0.1538 x 100

= 15.38%
