Can someone help me and explain how to do these probability questions?
2 answers:
a. The probability is 1/100 since there are 10 possible digits (0-9) and you need the last two digits so .
This is 1%.
b. Let's start by calculating the probability of getting the right digits knowing that they are both even.
We have a total of 5 even digits (0, 2, 4, 6, 8). You need the last two so which is 4%.
Therefore the answer is a) It increases the probability that your choice is correct to 1/25, or 4%, because each digit could be 0, 2, 4, 6 or 8.

Answer:
4
Step-by-step explanation:
If two variables are proportional then
...(i)
where, k is constant of proportionality.
The given equation is
...(ii)
where,
s = number of cups of seltzer.
c = cups of cranberry juice.
On comparing (i) and (ii), we get
Independent variable:
Dependent variable:
Constant of proportionality:
Therefore, the constant of proportionality is 4.
