Question

Ben has a basket of 5 red socks, 3 yellow socks, and 2 green socks. What is the theoretical probability that if he randomly selects a sock from the basket it will be red?

Answer 1

the probability of pen being red is,

$p=\frac{^5C_1}{10C_1}$

$p=\frac{5}{10}=\frac{1}{2}=0.5$

so the answer is 0.5
