YOu would take 7+12+18+5 and get 42 then subtract 12 from that you get 30 so you have 30/42 then simplify

The probability that the marble drawn will not be orange is option(A)  \(\frac{5}{7}\)

What is Probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given,

Number of red marbles = 7 marbles

Number of orange marble =12 marbles

Number of yellow marble = 18 marbles

Number of purple marbles = 5 marbles

Total marbles = 7+12+18+5 = 42 marbles

Total marbles without orange marble = 7+18+5 =30 marbles

Probability = Number of favorable outcome / Number of total outcome

Probability that the marble drawn will not be orange = \(\frac{30}{42}=\frac{5}{7}\)

Hence, the probability that the marble drawn will not be orange is option(A)  \(\frac{5}{7}\)
