Answer:

The chances of drawing a green card on your first try is 1/3

Explanation:

It is given that,

No. of black cards, n₁ = 3

No. of white cards, n₂ = 3

No. of green cards, n₃ = 3  

We have to find the probability of drawing a green card on the first try. Probability is given by :

P=\dfrac{no\ of\ favorable\ outcome}{total\ no\ of\ outcomes}

Here,

Total no of outcomes are 9 and no of favorable outcome is 3

So, P=\dfrac{3}{9}=\dfrac{1}{3}

Hence, the correct option is (d) " 1/3 ".

Why do land plants need to conserve water
erastova [34]

Answer: Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.

Explain the role convection plays in the rock cycle
Romashka-Z-Leto [24]

Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. All rocks are made up of minerals. A mineral is defined as a naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure. A rock is any naturally formed, nonliving, firm, and coherent aggregate mass of solid matter that constitutes part of a planet.
