This week in class we learned about probability. Probability means the odds of something
happening or not happening and is also a part of statistics. Probability is always between one and zero. Probability is in a fraction and should be reduced if could do so. This
week we mainly worked of probability of a deck of cards and two die being rolled.

Example 1:

What is the probability of picking a black diamond?

Since there is no black diamonds the answer would be 0/52 which reduces to 0.

Example 2:

What is the probability of rolling and even number if you roll
two die?

Since there is to die the possibility is out of 36. There are 6 even numbers so 6/36 reduces to
1/6.

Example 3:

What is the probability of picking a black card?

There are 26 black cards out of 52. So 26/52 which reduces to 1/2.
