Kayla has a bowl of beads that contains 42 yellow beads, 28 green beads, 12 white beads, and 18 red beads. she randomly draws a bead from the bowl.

the probability of kayla not drawing a yellow or a green bead %. the probability of kayla drawing a red or a green bead %.

A) probability of she not drawing a yellow beads or green beads is probability of she drawing red or white. Red+ white = 30. There are total of 100 beads. That means that asked probability is:
30/100

b) its oposite that result from a) yellow beads + green beads = 70
probability is:  70/100
