A researcher was tape recording birdcalls. The tape recorder had a 1-hourtape in it. Eight minutes after the recorder was turned on, a 5-minutebirdcall began. Unfortunately, the researcher accidentally erased 10 minof the tape. What is the probability that: a. part of the birdcall was erased? b. all of the birdcall was erased?(Hint: Draw a time line from to 60 min and locate on this line when thebirdcall took place. Also consider the possible starting times when the erasure could have occurred.)
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
