The actual result of this scenario would change depending on how much you simplify it. If you were to simply regard each key as having an equal probability of being struck, then you could say that each key has a 1/88 chance of being hit. That is, statistically speaking, if you were to hit the piano randomly 88 times you should hit each key once. However, this is probably not true in real life. From the vantage point you have over the piano, you are situated more comfortably over the middle range of keys. So this means that you will be more likely to hit those within your range of motion. Another facet to this is the predictability of human nature. Knowing that they will be expected to hit the keys that lie closer to them, the general person will deliberately reach out and hit a key further away from them to 'make it look random'. Contrary to their intent, this actually alters the probability of hitting the other keys, biasing the experiment.
the probability is put into a fraction for you. 4/10 which is simplified to 2/5. 2/5=40% the probability you will bowl a strike is 40%.

The number of trades depends on your personal goals for the day as well as the number of trading opportunities and your opportunities depend on your trading strategy. If you feel like you have reached your profit target with 1 trade then that is the only trade you should make that day. If you feel like you can make more then you trade more, but don't rush into trades have patience and wait for the right moment to strike.
there are several methods the easiest is just straight contextual multiplication: the 7th is a strike, he has 70% chance of hitting a strike 30% (chance he does not hit a strike) ^6th power (that's how many times he misses) * 70% (he hits the 7th) .3^ 6 * .7 = 5.103 * 10^(-4)
the probability is put into a fraction for you. 4/10 which is simplified to 2/5. 2/5=40% the probability you will bowl a strike is 40%.
Strike Outs
Not familiar with that particular terinology, but it likely refers to an assault. Since the word "battery" is included, it undoubtedly refers to hitting with some object other than your hands/fists.
By hitting it with a special type of stone, such as flint.
by hitting it with a back of a hammer
a general strike

Have your pitcher only focus on the strike zone. Have him/her think they are a hunter. A hunter looks into the scope and looks straight down the barrel. In this case the barrel is the line from the pitcher's eyes to the strike zone. If he or she looks at the strike zone and the catcher's glove only, they should not have a problem with hitting batters.
For the pitcher's ball/strike pitch numbers, it is counted as a strike.
the tree was the tallest object in the field!
