Answer 1

Answer:

Probability that the marble is not yellow = 5/12

Explanations:

Number of red marbles, N(Red) = 6

Number of blue marbles, N(Blue) = 4

Number of yellow maebles, N(Yellow) = 14

Total number of marbles, N(Total) = N(Red) + N(Blue) + N(Yellow)

N(Total) = 6 + 4 + 14

N(Total) = 24

Probability that the marble chosen is yellow, P(yellow) = N(yellow) / N(Total)

P(yellow) = 14/24

P(yellow) = 7/12

P(yellow) + P(not yellow) = 1

P(not yellow) = 1 - P(yellow)

P(not yellow) = 1 - 7/12

P(not yellow) = 5/12

Probability that the marble is not yellow = 5/12
