Are your numbers right?  Diana worked on her project for 613 hours, Gabe worked on it for 134 times as long as Diana, and Paula worked on her science project 34 times as long as Diana?  Assuming they are, It is false that Diana worked longer on her science project than Gabe worked on his.  Tell me if I read the question wrong, I am happy to help.

In a valid probability distribution, each probability must be between 0 and 1, inclusive, and the probabilities must add up to 1
lora16 [44]

The value of x is 1/5

Step-by-step explanation:

In a probability distribution, probability should be between 0  and 1. The probabilities add up to one.

Given probabilities are:

\frac{1}{10}, \frac{1}{5}, \frac{1}{2}, x

The sum of these probabilities will be equal to 1.

So,

To find x,

\frac{1}{10}+\frac{1}{5}+\frac{1}{2}+x = 1\\\frac{1+2+5}{10}+x=1\\\frac{8}{10}+x=1\\x= 1- \frac{8}{10}\\x = 1- \frac{4}{5}\\x= \frac{5-4}{5}\\x=\frac{1}{5}

The value of x is 1/5
