# Balls

From the bag with numbered balls (numbers 1,2,3,. ..20) we pick one ball. What is the probability of choosing a number containing 1?

Correct result:

p =  0.55

#### Solution:

$p=\frac{1+10}{20}=\frac{11}{20}=0.55$ We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you! Tips to related online calculators
