Answer:
a) blue = 1/6
b) white = 2/9
c) green or yellow = 11/18
d) neither blue nor yellow = 1/2
Step-by-step explanation:
First, you have to find the total marbles Maria has in the bag.
5 green + 3 blue + 6 yellow + 4 white = 18 marbles.
To find the probability you can use the formula:
probability = favorable outcomes / total number of possible outcomes
a) For blue
the amount of blue marbles are 3, so the probability is 3/18, simplifying the fraction you get 1/6.
b) For white
the amount of white marbles are 4, so the probability is 4/18, simplifying the fraction you get 2/9.
c) For green or yellow
the amount of green marbles are 5 and the amount of yellow marbles are 6, so the probability is 11/18.
d) neither blue nor yellow
the amount of blue marbles are 3 and the amount of yellow marbles are 6, so there are 9 out 18 that are not blue nor yellow, so the probability is 9/18, simplifying the fraction you get 1/2.
