Hi! is it perhaps possible if I could perhaps get some assistance with b) and c) below please? Question: The Air force receives 30% of its parachutes from company C1 and the rest from company C2. The probability that a parachute will fail to open is 0.0025 and 0.002, depending on whether it is from company C1 or C2, respectively. a) What is the probability that a randomly chosen parachute will fail to open (rounded off to four decimals)? Ans=0.0022 b) If a randomly chosen parachute fails, what is the probability it came from company C1 (rounded off to four decimals)? c) If a randomly chosen parachute fails, what is the probability it came from company C2 (rounded off to four decimals)?
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.
