From a barrel of colored marbles you randomly select 7 blue, 5 yellow, 8 red, 4 green, and 6 purple marbles. Find the experimental probability of randomly selecting a marble that is either green or purple. Write your answer in simplest form.
Isaac is wrong
To find the experimental probability of randomly selecting a marble that is either green or purple, we need to determine the total number of marbles that are green or purple out of the total number of marbles.
Given:
- Number of green marbles: 4
- Number of purple marbles: 6
- Total number of marbles: 7 blue + 5 yellow + 8 red + 4 green + 6 purple = 30 marbles
To find the probability, we add the number of green and purple marbles together:
4 green marbles + 6 purple marbles = 10 marbles
Now, we divide the number of green and purple marbles by the total number of marbles:
10 marbles / 30 marbles = 1/3
Therefore, the experimental probability of randomly selecting a marble that is either green or purple is 1/3.
So, the correct option is c) 10/30.
This Is a mutually exclusive event
Probability that green or purple will happen
Is the sum total of em
Pr(g or p)=(4+6)/30
