Let X be the number of times out of 3 I ask if I can go for the Australia fieldtrip.
The probability of a success=0.05

X~B(3, 0.05)

Expectation=np=(3)(0.05)=0.15

The expectation of my parents letting me go is only 0.15. But in the end, they really let me go. Haha. Miracles do happen.

Another one happened yesterday during PE. I ran 2km non-stop. First time in my 18 years of life. Haha. I hate long distance running. I perspired as though i went to shower with my clothes on.
