    It would be about 3% I got this because you first had to multiply the results by the amount of stars they had so like 7*3 is 21 and so on if you did this to all the pairs you would get 56 now divide 56 by the amount of restaurants 7+5+3 which is 15 so 56 divided by 15 is about 3%

    Ben found:

    7 ⭐️⭐️⭐️ restaurants

    5 ⭐️⭐️⭐️⭐️ restaurants

    3 ⭐️⭐️⭐️⭐️⭐️ restaurants

    A total of 15 restaurants

    Out of the 15 restaurants, 3 will be 5-star. So, 3/15, reduces to 1/5 and 1/5 as a percentage is 20%

    Ben's probability of choosing a 5-star restaurant at random is 20%
