Ajar contains 4 white and 4 black marbles. we randomly choose 4 marbles. if 2 of them are white and 2 are black, we stop. if not, we replace the marbles in the jar and again randomly select 4 marbles. this continues until exactly 2 of the 4 chosen are white. what is the probability that we shall make exactly n selections?

option: d is correct

step-by-step explanation:

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.
