Question

In a bag of marbles, you have 4 green, 3 yellow, 5 blue, and 8 red marbles. What is the probability of picking a green marble from the bag?
a) 3/20
b) 1/5
c) 1/10
d) 1/4

Answer 1

A) 3/20 
add up all of the marbles and whatever is asking you for possibilities is the number of marbles is given you already. for example. i have a ticket for a raffle. so i got only 1 and there is 25 people more with a ticket. what are my chances of winning? 1 out of 25 right?(1/25) because i got 1 ticket if i had 2 it would be 2 out of 25 or (2/25) hope this helps. :)

Answer 2

4 + 3 + 5 + 8 = 20

4 / 20 = 1/5
