There are 32 students in mrs. worrells classroom. there are 12 boys and 20 girls. she needs to select two students to represent she class for a math contest. she will put all her students names on a piece of paper and randomly select two names, one after the other. what is the possibility that she will select a boy first and then a girl? a. 1/4 b. 15/64 c. 15/62 d. 1/2

C. 15/62

Step-by-step explanation:

The probability of drawing a boy's name first is 12/32. Then the probability of drawing a girl's name is 20/31, assuming the boy's name was not replaced. The joint probabiilty is the product of these:

... (12/32)·(20/31) = (3·4·5·4)/(16·2·31) = 15/62

answer: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
