D:
Correct Answer
C
Explanation
To find the probability of selecting a blue or white bead, we need to calculate the total number of blue and white beads and divide it by the total number of beads in the bowl.Given the distribution of colors and their corresponding counts:Color: Blue, Black, Yellow, White, BrownCounts: 1, 2, 4, 5, 3The total number of blue and white beads is 1 + 5 = 6.The total number of beads in the bowl is the sum of all the counts: 1 + 2 + 4 + 5 + 3 = 15.Therefore, the probability of selecting a blue or white bead is 6/15, which simplifies to 2/5 or 0.4.So, the probability that a bead selected at random will be blue or white is 0.4 or 40%.
