3. Use the frequency distribution to construct a histogram, and match it with one of the histograms shown. 4. Match the frequency distribution of the weights in grams of pre-1964 quarters to the corresponding histogram.

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.)
