Answer:
2/5
Step-by-step explanation:
In probability, the probability something will happen and the probability that the same thing will not happen will have a sum of 1 (in proportion), because if an event occurs, it always either results in the marble being purple or not purple. Since they add up to 1, use:
3/5 + x = 1
Where x = 2/5.
Answer:
P(not purple) =2/5
Step-by-step explanation:
The total probability has to equal 1 for two events that are complements
P (purple) + P (not purple) =1
3/5 + P (not purple) =1
Subtract 3/5 from each side
3/5 -3/5 + P (not purple) =1-3/5
P(not purple) =2/5
