There are 8 blue marbles and 7 red marbles in a bag. julie pulls two marbles at random from the bag first. what is the probability that she first pulls a blue marble and then a red marble?

Step-by-step explanation:

Given: Number of blue marbles = 8

Number of red marbles = 7

Total number of  marbles = 8+7=15

Now, the probability that she first pulls a blue marble is given by :-

Now, total marbles left in bag = 15-1=14

Now, the probability that she second pulls a red marble is given by :-

Thus, the probability that she first pulls a blue marble and then a red marble is given by :-

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
