There is a 50.18% probability that they are of the same gender.
Step-by-step explanation:
We have these following percentages:
53% of the students are males.
47% of the students are females.
If two students from this college are selected at random, what is the probability that they are of the same gender?
The probability that each is male is 53%. So the probability of both being males is
The probability that each is female is 47%. So the probability of both being females is

Answer:
Step-by-step explanation:
The volume of a triangular pyramid can be found using the following formula:
Basically, we have to multiply 1/3, the height, and the base area.
We know that the base area is 8.2 square centimeters and the height is 4 centimeters.
Substitute the values into the formula.
Multiply 8.2 square centimeters and 4 centimeters.
- 8.2 cm² * 4 cm= 32.8 cm³
Multiply 1/3 and 32.8 cubic centimeters.
Round to the nearest tenth.
The 3 in the hundredth place tells us to leave the 9 in the tenth place.
The volume of the triangle pyramid is about 10.9 cubic centimeters.
