Acellus Find the expected value of a random variable x having the following probability distribution. 0 1 2 3 4 5 Probability 1/

barxatty [35]

Answer:

"2.25" is the right answer.

Step-by-step explanation:

According to the question,

The expected value will be:

= $\sum_{i=1}^{n} x_i P(X = x_i)$

= $0\times \frac{1}{8}+1\times \frac{1}{4}+2\times \frac{3}{16}+3\times \frac{1}{4}+4\times \frac{1}{6}+5\times \frac{1}{8}$

= $0+\frac{1}{4}+\frac{3}{8} +\frac{3}{4}+\frac{1}{4} +\frac{5}{8}$

= $\frac{1}{4} +\frac{8}{8} +\frac{4}{4}$

= $\frac{1}{4} +1+1$

= $0.25+2$

= $2.25$

Thus the above is the right approach.

Fitz and 3 friends are at the amusement park. Each person buys a pretzel for $4, cotton candy for $3, and a drink for $1. Write

Musya8 [376]

4x+3x+1x=t, where x represents the number of people, and t represents the total cost.

So to solve it, it says Fitz and 3 friends so that’s four people, you’d substitute x for 4.

I hope this helps!
