Answer:
0.5
Step-by-step explanation:
We can calculate the probability of picking a red marble by:
- adding all the marbles together
- then subtract the amount of red marbles by the number found previously.
2 + 3 + 5 = 10
10 - 5 = 5
5 is what of 10?
5 is 50% of 10.
50% means 0.5 out of 1.
Your answer is 0.5.
Hope this helps. Have a nice day.
