I've tossed three coins 128 times and i have the following numbers of heads, tails, excuse me, heads 0 through 3.
00:09
So 12 times head, 3 heads in a row.
00:12
Now the experimental or the empirical probability, the probability of these is going to be the out of the 25 out of 128, the 50 out of 128, 41 out of 128, and 12 out of 128.
00:33
And 25 divided by 128 gives us a probability of approximately 0 .195.
00:42
For the next, for 50, that's going to be twice as big.
00:45
That's going to be 0 .391.
00:49
For 41, that is a probability of 0 .320.
00:56
And then finally that 12 out of 128 is 0 .09 and we're around to 4.
01:05
Now the probabilities, the theoretical probability of these is this is a binomial situation and we have n being 3 and the probability of success is this 1 half...
