A bag has 5 yellow marbles, 3 red marbles, and 2 blue marbles. Quinn randomly picks a marble from the bag and returns it before
another is picked. How many times would Quinn expect to pick a blue marble if he picks a marble 200 times? O A 20 B. 40 C 50 O D. 60 O E 100
1 answer:
<u><em></em></u>
<u><em>Answer⇒⇒⇒40 blue marbles</em></u>
Step-by-step explanation:
First find the probability of a blue marble
P (blue) = number of blue marbles / total marbles
= 2 blue/ ( 5+3+2) total
= 2/10
=1/5
We can use this since we return the marble to the bag each time
We multiply this by 200 for the number of times it is picked
200 * 1/5 = 40
We should expect to pick 40 blue marbles

Using y=mx+b
m stands for slope, b stands for y-intercept
slope is rise/run, the y-intercept is the point where the line touches the y-axis
1- y=(4/6)x+(-2)
2- y=(-2)x+(3)
