The probability of randomly picking out a red marble is 1/5
To determine the probability of randomly picking out a marble and it being red, we need to consider the total number of marbles and the number of red marbles.
Total marbles = 5 green + 3 blue + 2 red = 10 marbles
Red marbles = 2
So, we have
Probability = (Number of favorable outcomes) / (Total possible outcomes)
This gives
Probability = (Number of red marbles) / (Total marbles)
By subsituition
Probability = 2/10 = 1/5
Hence, the probability of randomly picking out a marble and it being red is 1/5

Answer:
1/5
Step-by-step explanation:
Since there are 2 red marbles and since there are a total of 10 marbles, the probability is 2/10. This simplifies to 1/5. So the probability of picking a red marble is 1/5.

Part A
Write expressions for the number of dollars Ivan pledged and the number of dollars Vicky
pledged. Use m for the number of miles that Jana bikes.
Part B
Add the two expressions from Part A to find the combined amount that Ivan and Vicky
pledged in terms of m.
Part C
Find an expression equivalent to the one from Part B by factoring out the greatest common
factor from the two terms.
Ivan: $4.25 + $1.25m
Vicky: $5.75 + $0.75m
where m is the number of miles jana bikes
Total = ($4.25 + $1.25m) + ($5.75 + $0.75m)
Total = $4.25 + $5.75 + $1.25m + $0.75m
Total = $10.00 + $2m
Total = $2 (5+m)
