Question

a number cubes tolled 450 times. the number 3 comes up 67 times. what I's the theoretical probability of rolling a 3 ? WRITE YOUR ANSWER AS A FRACTION b. what us the experimental probability of rolling a 3 ? write your answer as a fraction

Answer 1

assuming number cube has 6 sides

probablity is (desiredoutcomes)/(total possible ouctomes)


since it is 450 times
total possible outcomes=450

experimiental probablity is the one actaully obtained by doing it
theoretical is the predicted amount

so theoretical probablity of rolling a 3 is 1 number out of 6 or 1/6 or 75 times out o 450 times

experimiental is the actaull one so67 out of 450 or 67/450

theoretical is 1/6 or 75/450
experimental is 67/450
