19 quantities of item A and 6 of item B were sold, respectively
<h3>How to determine the quantity sold</h3><h3>The missing information in the question are</h3>
- The cost of item A is $4 and
- The cost of item B is $2.
Using the information and the given parameters, we have the following system of equations:
A + B = 25
4A + 2B = 88
Multiply the first equation by 2
2A + 2B = 50
Subtract this equation from the second equation to eliminate B
2A = 38
Divide both sides by 2
A = 19
Substitute A = 19 in A + B = 25
19 + B = 25
Subtract 19 from both sides
B = 6
Hence, 19 quantities of item A and 6 of item B were sold, respectively

40=10+3*10
so the amount of f at 40 is the similar at 10 or
f(40)=f(10)=13
Hey, so x would be -10. If I need to type the work out I can just let me know.
A binomial distribution can only be used when there are 2 possible outcomes, no more, no less.
Looking at the situations given you are able to use a binomial distribution in 2 cases.
First is the quarter being flipped 3 times. There are only two possibilities (Heads or Tails).
Second is the 3 marbles being pulled out of the bag. There are only two types of marbles (Green and Blue).
