40. Mari has 42 green beads, 30 yellow beads, and 54 blue beads. She wants to use all of the beads and
string the beads so that she has the same number of
each color on a string of beads. What is the greatest
number of strings of beads she can make?

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.)
