Computing for probabilities

Question
When Paula played softball, she struck out twice, walked 3 times and had 6 hits. The probability she will get a hit the next time she is at bat is ____ out of ______.




Solution
First, count the number of times Paula played or she was at bat. ANSWER: 11 times
Second, count the number of times she had a hit. ANSWER: 6 times
Hence, the probability that Paula will have a hit next time she is at bat is 6/11 or 0.55 OR 55 out of 100 OR 55 per cent probability.
