Money Eric returned from a trip to Las Vegas with $300.00, which was 50% more money than he had at the
beginning of the trip. How much money did Eric have at
the beginning of his trip?

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
