There is a bag with 50 popsicles inside. 5

Allisa [31]

Answer:

25%

Step-by-step explanation:

We know that there are ten purple popsicles. Together without the purple popsicles, there are 40 popsicles in total. Therefore there is a 10/40 chance to get purple. We need to turn this into a percentage so we do (10 / 40) x 100. This would equal to 25%, therefore, there is a 25% probability to get a purple popsicle.

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.
