Question

If we toss a coin 100 times, then Heads must appear exactly 50 times.

True
False

Answer 1

This is false.

Answer 2

False, theoretically it will be heads 50% of the time in the long run but in short experiments it will vary

Answer 3

try the experiment enough times and you'll see that you probably never get exactly 50/50 in 100 tosses
so false

Answer 4

false
try it 10 times.

Answer 5

Suppose statistics say that 1 in 1,000,000 people win the lottery. Then, were that true, if I were to buy 1,000,000 tickets, I'd win.

Answer 6

TT and Truman are exactly right. Try this yourself. Take a coin; toss it 10 times; do you get 5? Try it again; do you get 5?

Answer 7

You taught me that way of approaching the idea James, back when I first found this site :)
But I would have known this is false anyway.

Answer 8

if you're doing probability, something fun to consider would be quantum tunneling.
