Answers
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

The given bamboo can grow 0.6 feet in five days.
Ratio and Proportion
You can use the provided rate to calculate how many feet the bamboo plant could grow in 0.5 days. You can set up a proportion to determine the growth in 0.5 days if the plant grows 1.2 feet in one day.
So we can have 1.2 * 0.5 = x to represent the growth in 0.5 days.
x = 1.2 * 0.5
x = 6.0
As a result, at the specified rate, the bamboo plant might grow 0.6 feet in 0.5 days.
