A bag contains 20 marbles of the same size that are blue, green, and red. The probability of picking a blue marble is 20%. The probability of picking a green marble is 50%. Determine the probability of picking a red marble from the bag and then classify the probability of picking a red marble as likely or not likely to occur.

Answer:

The chance would be 30% because 50+20=70 and then you do 100-70=30 Also 30 is below 50 so it would be not likely to be often picked.

Answer:

30% of picking a red marble, it is likely to occur.

Explanation:

50% of green and 20% of blue. The most logical is to add to 100%. 50+20=70, 100-70=30. Thats the 30% of red. Since red is 10% than blue, it is likely to get a red marble.
