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 is
%. the probability of kayla drawing a red or a green bead is
%

Add all bead colors up

42+28+12+18=100

add up yellow and green

42+28=70

now find out how many beads are not yellow or green by subtracting that from 100

100-70=30

so the first answer is 30/100 -> 3/10 -> 30%

now add up red and green beads

28+18=46

so your next answer is

46/100 -> 23/50 -> 46%
