Please help solve these problems step by step so I could learn the routine myself. Thank you! According to a survey of hikers on a trail, 50% of the hikers like Gatorade (G) and 40% like energy bars (E). 20% like both. Assume random selection: Find the probability that a hiker likes Gatorade or energy bars If a hiker likes Gatorade, find the probability that he likes energy bars If a hiker likes energy bars, find the probability that he likes Gatorade.
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.

According to a survey of hikers on a trail, 50% of the hikers like Gatorade (G) and 40% like energy bars (E). 20% like both. Assume random selection:
- Find the
probability that a hiker likes Gatorade or energy bars - If a hiker likes Gatorade, find the probability that he likes energy bars
- If a hiker likes energy bars, find the probability that he likes Gatorade.
Given:
Probability for the G (Gatorade) and E (Energy)
2.
70% probability that the researcher likes Gatorade or energy bars.
