The probability of randomly getting first a red marble and then a blue marble is:
P = 0.083
<h3>
How to find the probability?</h3>
There are:
- 3 blue marbles
- 2 red marbles
- 4 yellow marbles.
For a total of 9 marbles.
The probability of getting a red marble is equal to the quotient between the number of red marbles and the total, so:
P(red) = 2/9
Then the probability of getting a blue marble is equal to the quotient between the number of blue marbles and the total, but because we already took one marble, now the total is 8.
P(blue) = 3/8
The joint probability is given by the product:
P = (2/9)*(3/8) = 0.083

Answer:
The 2nd deal is better
Step-by-step explanation:
First you divide the chicken nuggets by the price and then find how much one chicken nugget costs. In this case $10 divided by 8 is $1.25 while $7.50 divided by 5 is $1.50. The first deal costs more for one chicken nugget so deal 2 is better

Answer:
Chair $280
Loveseat $560
Couch $ 1,160
Step-by-step explanation:
chair = x
loveseat=2x
couch = 2x + 600
x +2x + 2x +600 = 2000
5x + 600 =2000 subtract 600 from both sides
5x =1400 divide by 5
x = $280
Chair is the value of x =$280
Loveseat is twice the value of x = 2 x $280 =$560
Couch is twice the value of x plus $600 = $560 + $600
