type the correct answer in each box. 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 % .
Answer
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 $P_1=\frac{30}{100}\times100% = 30%$
Step3: Calculate probability of drawing red or green
Number of red or green beads is $28 + 18=46$. Probability $P_2=\frac{46}{100}\times100%=46%$
Answer:
30, 46
