A bag contains 6 red marbles, 6 white marbles, and 4 blue marbles. Find P( red or blue)
To find the probability of selecting a red or blue marble from the bag, we need to first determine the total number of marbles in the bag.
Total number of marbles = 6 red + 6 white + 4 blue = 16 marbles
Next, we need to determine the number of favorable outcomes, which in this case is the number of red marbles or blue marbles in the bag.
Number of red marbles = 6
Number of blue marbles = 4
Number of favorable outcomes = 6 red + 4 blue = 10 marbles
Now we can calculate the probability:
P(red or blue) = Number of favorable outcomes / Total number of outcomes
P(red or blue) = 10 / 16
P(red or blue) = 5 / 8
Therefore, the probability of selecting a red or blue marble from the bag is 5/8.
