Given, total rods = 75

Color	Total	Twisted	Clear
Blue	35	25	10
Red	40	30	10

Now, we will find the probability.

A. Probability of a blue rod from the box = $\frac{T o t a l b l u e r o d s}{T o t a l r o d s} = \frac{35}{75} = \frac{7}{15}$

B. Probability of a clear rod from the box = $\frac{T o t a l b l u e r o d s}{T o t a l r o d s} = \frac{10 + 10}{75} = \frac{20}{75} = \frac{4}{15}$

C. Probability of a blue twisted rod = $\frac{T o t a l b l u e r o d s}{T o t a l r o d s} = \frac{25}{75} = \frac{1}{3}$

D. Probability of a clear red rod = $\frac{T o t a l b l u e r o d s}{T o t a l r o d s} = \frac{10}{75} = \frac{2}{15}$

E. Probability of a twisted rod = $\frac{T o t a l b l u e r o d s}{T o t a l r o d s} = \frac{25 + 30}{75} = \frac{55}{75} = \frac{11}{15}$

You need to be content with small steps. That's all life is. So, when you look back down it all adds up and you know you covered some distance. It look me a long time to accept that, but it's true. You need to have patience. The best kind of people is the ones in your life who help you see the sun where once you just say clouds. You should value those people who believe in you and help you see your worth: so you start to believe that you are valuable, as well. (Translate into Bangla)

Globalization is very important in international relations. Basically it is a process of expanding trade and commerce all over the world by creating a border less market.

They can even share immediately come to its assistance. But taking advantages of the idea of globalization, capitalism seems to be on triumphant march. It is creating more opportunity for capitalist countries rather than for the developing ones.

Translation : English to Bangla:Natural disasters as we all know are the consequences of events triggered by natural hazards that overwhelm local response capacity and seriously affect the social and economic development of a region. There is basically no human control over the natural disaster. We cannot stop these natural disasters but what is in our hands is to be prepared for these. Also, there are a lot of ways through which we can minimize the damage caused due to these natural disasters. Traditionally, natural disasters have been seen as situations that create challenges and problems mainly of a humanitarian nature. There is no way to prevent or avert these natural disasters, though scientists do claim to have found the ways to predict these natural disasters at most of the times they have failed to predict natural disasters causing some serious destruction.
