The probability is 15/25 = 3/5
What else can I help you with?
There are 10 boys and 12 girls in a class if one student is selected at random from the class what is the probability it is a girl?
The probability is the number of girls divided by the number of students, so 12/22, or 6/11
A group of 12 male and 4 female students is planning to go for pizza If 50 percent of the male students go and 25 percent of the female students go find the probabity that a random student is female?
50% of 12 male students = 6 25% of 4 female students = 1 So in total 7 students go for pizza. The probability that a randomly selected student will be female is 1/7 or 14%.
A circle is inscribed in a square with a side length of 4 If a point in the square is chosen at random what is the probability that the point is in the square but not in the circle?
21.5%
Does the probability that a continuous random variable take a specific value depend on the probability density function?
No. The probability that a continuous random variable takes a specific value is always zero.
What is the probability the random variable will assume a value between 40 and 60?
It depends on what the random variable is, what its domain is, what its probability distribution function is. The probability that a randomly selected random variable has a value between 40 and 60 is probably quite close to zero.
If there are 45 students in a biology class and 23 are girls what is the probability that a student chosen at random will be a boy?
Probability that a girl is chosen = 23/45 = .511 So, the probability that a boy is chosen = 1 - .511 = .489
A class of 25 students has 15 girls and 10 boys If one student is chosen at random What is the probability it is a girl?
The probability is 15/25 = 3/5
What is the probability for a student in a dormitory to be selected if 10 percent of the students live in dormitories and a random sample of 100 is selected?
The probability is 10 percent.
In a classroom the students are 11 boys and 1 girl if one student is selected at random find the probability that the student is a girl?
There is only one girl out of 12 students so the probability that the girl is selected is 1/12.
On a math test 5 out of 20 students got an A If three students are chosen at random what is the probability that all three got an A on the test?
P( a student getting an A) = 5/20=1/4 There are 3 students. The probability that all three got an A is (1/4)(1/4)(1/4)=1/64.

In a classroom the students are 11 boys and 1 girls If one student is selected at random find the probability that the student is a girl?
1/12 =0.08333... ≈ 8.3%
Two students are chosen at random from a class of 30 what is the probability that both you and your best friend are chosen?
The probability of this is based heavily on whether or not said best friend is even in the class. If both are in, it's a 1/870 chance.Ê
What are chosen at random from a standard deck of cards with replacement what is the probability of getting to aces?
"Playing cards" are chosen at random.

What is the probability that an f2 seed chosen at random will be yellow?
3/4
There are 10 boys and 12 girls in a class if one student is selected at random from the class what is the probability it is a girl?
The probability is the number of girls divided by the number of students, so 12/22, or 6/11
