Theoretical Probability - Guided Practice#10 - The bag contains 4 red, 1 yellow, 2 blue, 6 purple, and 3 green marbles. Find theprobability of picking a marble that is not a red marble.O 60%O 45%25%75%

Answer 1

75%

Step-by-step explanation:

The number of red marbles, n(R) = 4

Total number of marbles, n(S) = 4+1+2+6+3 = 16

The probability of not picking a red marble, P(R'):

`\begin{gathered} P(R^(\prime))=1-P(R) \\ =1-(n(R))/(n(S)) \\ =1-(4)/(16) \\ =1-(1)/(4) \\ =(3)/(4) \\ =0.75 \\ =75\% \end{gathered}`

The probability of picking a marble that is not a red marble is 75%.
