3 female students and 7 male students are nominated for scholarships.  All 10 students are equally qualified and equally likely to be chosen.  You may assume any person can receive a maximum of one scholarship.  You are awarding a total of 3 scholarships.  What is the probability that all the scholarships are given to females?  

0.21 or 21/100

Step-by-step explanation:

the chance of a female student getting a scholarship is 7/10. now that student already has a scholarship so now there are 9 students. the probability of the next female getting a scholarship is 6/9. and then the next is  5/8

7/10 x 6/9 x 5/8 = 21/100 or 0.21

answer: it's d

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
