Abag contains 10 red marbles, 15 yellow marbles, 5 green marbles, and 20 blue marbles. five marbles are drawn from the bag. what is the approximate probability that exactly two of the five are blue? 1% 4% 36% 40%

There are 20 blue marbles and 30 other than blue marbles.

Probability of drawing blue marble is 20/50 = 0.40

Probability of drawing other than blue marble is 30/50 = 0.60

Using the Binomial theorem, The probability of exactly 2 blue ball out of 5 is given by

5C2 0.40^2 0.60 ^3

= 10 * 0.40^2 * 0.60^3

= 10 * 0.16 * 0.216

= 0.3456

= 36% approx

36%

Step-by-step explanation:

got it right

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
