probability of an event from experimental data will need to
- 00:24
make a ratio The probability of an event happening is
- 00:26
the number of times the event occurred during the total
- 00:29
number of trials Well we want to know the probability
- 00:32
of flipping heads so let's start with the number of
- 00:34
times mercedes flipped heads Well she flipped tails four hundred
- 00:37
fifty times and she flipped heads one thousand fifty times
- 00:41
probability then is a thousand fifty over the fifteen hundred
- 00:44
of trials or point seven or seventy percent So yeah
- 00:47
pretty good odds to get ahead if she calls out
- 00:50
eds Yeah so that's it The answer is c or 00:00:53.029 --> [endTime] shmoop
