A bag contains 5 red marbles, 1 blue marble, 3 yellow marbles, and 2 green marbles. One
marble is drawn from the bag. What is the probability that the marble is red or yellow?

8/11

Step-by-step explanation:

5 red marbles, 1 blue marble, 3 yellow marbles, and 2 green marbles.

The total number of marbles is 11

P(red or yellow) = (number of red or yellow) / total

                           = (5+3)/ 11

                           = 8/11

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7
