Parenthesis first
19- (4+2) - 15 / 3
19-(6)-15 / 3
then division
19-6-5
then subtraction from left to right.
19-6= 13
13-5= 8
your final answer is 8
Answer:
13.33%
Step-by-step explanation:
First we need to find the total number of marbles
4 blue marbles+ 3 green marbles+ 7 red marbles+ 1 yellow marble= 15
The probability of a red marble = number of red marbles over the total marbles
P(red) = red/total = 7/15
We keep the marble. There are now 6 red marbles
4 blue marbles+ 3 green marbles+ 6 red marbles+ 1 yellow marble= 14
We have 14 marbles in the bag
The probability of a blue marble = number of blue marbles over the total marbles
P(blue) = blue/total = 4/14 = 2/7
Then we multiply the probabilities together
P(red,blue0 = 7/15 * 2/7 = 2/15 =.13333333 = 13.33%
