Anumber cube us rolled 450 times. the number 3 comes up 67 times. (a) what is the theoretical probability of rolling a 3? write your answer as a fraction in simplest form.(b) what is the experimental probability of rolling a 3? write your answer as a fraction in simplest form

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
