If a coin is tossed 8 times what is the probability that it will land on heads exactly four times?
You can use a tree diagram or a binomial:
I choose a binomial:
8!/(4! * 4!) * .5^4 * .5 ^ 4
70 ways 8 flips can end in 4 v 4, * chance of 4 heads, * chance of 4 tails = .2734375 ~ 27.34 percent.
What is the probability of tossing 4 pennies and landing on heads twice and tails twice?

How do you get statistic data about economy?
First decide what you want. The economy encompasses employment and unemployment, incomes and wealth, output and sales, international trade, investment, company formation etc. Within each one of these broad topics there are many hundreds (or thousands) of sets of data. Some of these may be relevant to the question at hand while others will not.
Most countries have a National Statistical Office or an Government Economic Department that will collect and publish data on their economy. Additionally, international and pan-national bodies like the United Nations, World Bank, International Monetary Fund (IMF), Oragnisation for Economic Cooperationand Development (OECD), Eurostat also collate and publish figures for member states. Most of these data are available over the internet.
