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
