Question 1

What is probability?

L4 S20

Answer 1

The likelihood of the occurrence of a particular event.

Question 2

In a population, if the probability of being blood-type A is 1/8 and the probability of being blood type-O is 1/2, what is the probability of being either blood-type A or O?

L4 S24

A. 5/8
B. 1/2
C. 1/8
D. 1/16

Answer 2

A. 5/8

Question 3

What is the binomial expansion formula?

L4 S29

Answer 3

(p+q)^n

p/q are the probability of one of two events occurring, the sum of which is 1

n is the number of events

Question 4

What is Chi-square goodness of fit?

L4 S39

Answer 4

Statistical test determining the probability that observed differences are due to chance.
