# Math Help - probability

1. ## Probability

Shannon flipped a coin 50 times, and it came up heads 27 times. What is the relative frequency of tails?

A) 46%

B) 50%

C) 54%

D) 85%

2. ## Re: probability

The frequency of tails added to the frequency of heads must equal 1, use this fact to find the frequency of tails
The relative frequency of tails is the frequency of tails divided by the frequency of head.
