Question

you randomly choose a shirt off the shelf. there is 4 blue shirts 2 black shirts and 2 black shirts and 2 green shirts and 1 white shirt and 1 red shirt.

Answer 1

To find the probability of choosing a red shirt, we have to divide the numbers of red shirts by the total number of shirts.

$P_{\text{red}}=\frac{1}{4+2+2+2+1+1}=\frac{1}{10}$

Hence, the probability of choosing a red shirt is 1/10
