Answer
Step-by-step explanation:
divide 48:6 first -> 15 + 25 = 5 - 8+4 - 2
then solves the right side of this equation from left to right -> 15 + 25 = -1
add 15 + 25 -> 50 = -1
switch -1 place -> 51 = 0
Answer:
40 blue marbles
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
