Nandini's phone battery dies as she is driving to her hometown. She knows that there are two 4− way junctions before reaching her hometown. So, she drives on until she reaches a four way junction and arbitrarily chooses one of the ways in front of her, and at the next four way junction, she again randomly chooses one of the ways in front of her. What is the probability that Nandini will reach her hometown without having to head back? Enter the answer up to 2 decimals accuracy.
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.
