At a popular rock-climbing site in Yosemite National Park, a randomly selected sample of $200$ climbers are asked whether they have ever had a climbing accident and whether they are certified climbers. The results are shown below. Suppose you are searching for a climbing partner at Yosemite and you meet Rob, Andrew, and Sarah. Rob thinks of himself as a free spirit $-$ he climbs without any certification. Andrew is hoping to continue his life-long streak of never having a climbing accident. You don't know anything about Sarah. **Use the frequency table below to calculate the following probabilities.** Round to the nearest *hundredth* of a percent. Probability that Rob has had an accident $=$ [[☃ input-number 1]] $\%$ Probability that Andrew is certified $=$ [[☃ input-number 2]] $\%$ Probability that Sarah is certified $=$ [[☃ input-number 3]] $\%$ |Certified | Not certified| Row total - | - | - **Has had an accident** |$2$ |$6$| $8$ **Has never had an accident** | $138$|$54$ |$192$ **Column total** |$140$ | $60$ |$200$
