In bag 1: There are 5 red balls and 3 green balls.

In bag 2: There are 4 red balls and 6 green balls.

Now,

In case 1, the probability of getting red ball from bag I and green ball from bag

2=55+3×64+6=56×610=3060

And, In case 2, the probability of getting green ball from bag I and red ball from bag

2=38×410=1280

∴Probability of getting 1 red ball and 1 green ball = 3080+1280=30+1280=4280=2140 (answer).

Precis writing: Ericsson and his colleagues then compared amateur (অপেশাদার ক্রিড়াবিদ) pianists with professional pianists. The same pattern emerged. The amateurs never practiced more than about three hours a week over the course of their childhood, and by the age of twenty they had totaled two thousand hours of practice. The professionals, on the other hand, steadily increased their practice time every year, until by the age of twenty they, like the violinists (বেহালাবাদক), had reached ten thousand hours. The striking thing about Ericsson's study is that he and his colleagues couldn't find any “naturals” musicians who floated effortlessly to the top while practicing a fraction of the time their peers did Nor could they find any "grinds". people who worked harder than everyone else, yet just didn't have what it takes to break the top ranks. Their research suggests that once a musician has enough ability to get into a top music school, the thing that distinguishes (দু'টি জিনিসের মধ্যে পার্থক্য শোনা, দেখা, বোঝা) one performer from another is how hard he or she works. That's it. And what's more, the people a the very top don't work just harder or even much harder than everyone else. They work much, much harder.The idea that excellence at performing a complex task requires a critical minimum level of practice surfaces again and again in studies of expertise. In fact, researchers have settled on what they believe is the magic number for true expertise: ten thousand hours. The emerging picture from such studies is that ten thousand hours of practice is required to achieve the level of mastery associated with being a world- class expert-in anything, writes the neurologist Daniel Levitin. In a study after study, of composers, basketball players, fiction writers, ice skaters, concert pianists, chess players, master criminals, this number comes up again and again. Of course, this doesn't address why some people get more out of their practice sessions than others do. But no one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery.Instruction: Write a summary of the above passage with an appropriate title in the stipulated space.
