Answer 1

To find the value of x, we need to sum up the probabilities for Y, C, A, R, E, and S, and since the total probability should be equal to 1, we can set up the equation as follows:

0.25 + 0.18 + 0.30 + 0.17 + x = 1

Simplifying the equation:

0.90 + x = 1

x = 0.10

Therefore, the value of x is 0.10.
