Find the probability that you will roll an even number exactly 5 times when you:

roll a six-sided number cube 10 times.
P =
roll a six-sided number cube 20 times.
P =

Respuesta :

Answer:

roll a six-sided number cube 10 times.

     P = 0.246

roll a six-sided number cube 20 times.

     P = 0.015

Explain why the second result is less.

As the number of trials changes, the distribution changes

Step-by-step explanation:

just did it on edge

The respective probabilities when the dice is rolled 10 times and 20 times are; 0.246 and 0.015

What is the Probability?

A six sided cube has 3 even number and 3 odd number.

roll a six-sided number cube 10 times.

Using binomial probability distribution calculator online with the formula;

P(X = x) = ⁿCₓ * pˣ * (1 - p)^(n - x)

Probability of getting an even number for each roll = 0.5. Thus;

P(X = 5) = 0.246

B) Using the same concept and from online calculator;

Probability you will roll an even number exactly 5 times when you roll a six-sided number cube 20 times is;

P(X = 20) = 0.015
