Answer:
Step-by-step explanation:
In order to solve for "x", we must remember the following properties:
If , then
If , then
Therefore, knowing these properties, we can solve for "x" to find its value.
First, we need to subtract from both sides of the equation. Then:
And finally, we can divide both sides of the equation by 6. Then we get:
Answer:
B. 0.132
Step-by-step explanation:
For each time the dice is thrown, there are only two possible outcomes. Either it lands on a five, or it does not. The probability of a throw landing on a five is independent of other throws. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Timothy creates a game in which the player rolls 4 dice.
This means that
The dice can land in 6 numbers, one of which is 5.
This means that
What is the probability in this game of having exactly two dice or more land on a five?
In which
So the correct answer is:
B. 0.132
