Question

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 %.

Explanation:

Step1: Calculate total number of beads

$42 + 28+12 + 18=100$

Step2: Calculate probability of not drawing yellow or green

Number of non - yellow and non - green beads is $12 + 18=30$. Probability $P_1=\frac{30}{100}=0.3 = 30\%$

Step3: Calculate probability of drawing red or green

Number of red or green beads is $28+18 = 46$. Probability $P_2=\frac{46}{100}=0.46=46\%$

Answer:

30; 46
