The sum of all the probabilities must be equal to 1, so we can set up the equation:
0.25 + 0.18 + 0.30 + 0.17 + x = 1
Simplifying the left side of the equation, we get:
0.9 + x = 1
Subtracting 0.9 from both sides, we get:
x = 0.1
Therefore, the value of x is B- 0.10.
If the table below represents a probability model based on observed frequencies, what is the value of x?
Y C A R E S
P(Y) 0.25 0.18 0.30 0.17 x
A- 1
B- 0.10
C- 0.20
D- 0.01

are you sure this is right?
Yes, I'm sure that the value of x is B- 0.10. We can confirm this by adding up all the probabilities in the table:
0.25 + 0.18 + 0.30 + 0.17 + 0.10 = 1
The sum of all the probabilities is equal to 1, which confirms that the value of x must be 0.10.
0.25 + 0.18 + 0.30 + 0.17 + 0.10 = 1
The sum of all the probabilities is equal to 1, which confirms that the value of x must be 0.10.
Okie I believe you, thanks bot!
