A jar contains 5 red, 3 green, and 2 yellow marbles. If one marble is drawn at random, what is the probability that it is either red or green?

A jar contains 5 red, 3 green, and 2 yellow marbles. If one marble is drawn at random, what is the probability that it is either red or green?

Step 1: Count the number of red marbles. There are 5 red marbles.
Step 2: Count the number of green marbles. There are 3 green marbles.
Step 3: Count the number of yellow marbles. There are 2 yellow marbles.
Step 4: Add the number of all marbles together: 5 (red) + 3 (green) + 2 (yellow) = 10 total marbles.
Step 5: Add the number of favorable outcomes (red or green): 5 (red) + 3 (green) = 8 favorable outcomes.
Step 6: Calculate the probability by dividing the number of favorable outcomes by the total number of marbles: 8 (favorable) / 10 (total) = 4/5.
Step 7: The final answer is that the probability of drawing a red or green marble is 4/5.

Probability – The likelihood of an event occurring, calculated as the number of favorable outcomes divided by the total number of possible outcomes.
Favorable Outcomes – The outcomes that satisfy the condition of the event we are interested in, in this case, drawing a red or green marble.
Total Outcomes – The total number of possible outcomes, which is the sum of all marbles in the jar.
