What is Probability? What is Statistics?
a measure of how likely it is that a mathematical science relevant
some event will occur; a number to the collection, analysis,
expressing the ratio of favorable interpretation or explanation, and
cases to the whole number of presentation of data.

Good evening CounterTerrorist. I have
commanded my terrorist team to plant
a bomb somewhere in your training
facility. The only way to defuse the
bomb is to answer these 5 questions
that will help you figure out the 5 digit
codes.
Remember... if the bomb has been
successfully defused, then we will
surrender our weapons to you.
However, if you fail to defuse it, the
victory will be ours. You will
surrender the rest of your weapons
and you will be in our control.
Click on the link on top and set your timer
to 15 minutes only. When time runs out
then you're out of luck and the last laugh will be
mine.
8. 1. In the game of Counter Strike there are two teams
battling against each other. The Counter Terrorist and
the Terrorist. In this case the Terrorist need to plant the
bomb at the BOMBSITE. In order to do this they need
to take short routes to reach their destination and plant
the bomb. So now the terrorists need to find the
shortest route.
a.) How many ways can you go to T
SPAWN to the Bombsite?
b.)How many ways can you get to the
bombsite without going through the
enemies territory?
c.) What is the probability that you
will not walk through the enemy
territory?

defective pistols in one week?
'S' and 'F' (Success and Failure) are the possible outcomes of a
trial in a binomial experiment, and 'p' and 'q' represent the
probabilities for 'S' and 'F.'
• P(S) = p • P(F) = q = 1 p
• n = the number of trials
• x = the number of successes in n trials
• p = probability of success
• q = probability of failure
• P(x) = probability of getting exactly x successes in n trials
Remember that 'Success' in this case, is the probability of selecting a
defective pistol.
