As students walk into mr. jackson's class, they are randomly handed either a blue, yellow, green, or red card. if there are 8 boys and 12 girls in the class, what is the probability that the student chosen by mr. jackson will be a boy with a green card? a. 1/8  b. 1/16  c. 2/15 d. 1/5

we are given

Event-A:

they are randomly handed either a blue, yellow, green, or red card

so, total number of cards =3

probability of selecting green cards = (number of green card)/(total number of cards)

probability of selecting green cards is

Let's assume

Event-B:

there are 8 boys and 12 girls in the class

total number of students =8+12=20

number of boys =8

probability of a boy = (number of boys)/(total number of students)

Since, events A and B are independent

so,

probability that the student chosen by Mr. Jackson will be a boy with a green card = p(A)*p(B)

probability that the student chosen by Mr. Jackson will be a boy with a green card =

probability that the student chosen by Mr. Jackson will be a boy with a green card is ...........Answer

20335+282=20617

step-by-step explanation:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
