Answer:
<h2>31.25%.</h2>Step-by-step explanation:
The experimental probability is the ratio between the number of times an event occurs and the total number of trials.
In this case, the total number of trials is 64, because Page roles it 64 times.
Notice that the probability is about one event or the other, that indicates we need to sum both events.
Multiplying by 100, we have a probability of 31.25%.
Therefore, the experimental probability of getting three or four is 31.25%.

we have
The compound inequality can be divided into two inequality
-----> inequality A
----> inequality B
Solve inequality A
Divide by -3 both sides
when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
Rewrite
The solution of the inequality A is the interval (-∞,-3]
Solve the inequality B
Divide by -3 both sides
when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
The solution of the inequality B is the interval [-6,∞)
The solution of the compound inequality is
[-6,∞) ∩ (-∞,-3]=(-6,-3]
