In a paper bag, 4 of the 15 ribbons are purple. in a cloth bag, 1 of the ribbons is purple. if violet chooses one ribbon from each bag at random, what is the probability she will choose a purple ribbon from the paper bag and a purple ribbon from the cloth bag?

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.
