Answer:
The likelihood that neither of the stocks will rise is 0.14.
Explanation:
According to the Complement Rule, the combined probabilities of an event and its complement total 1.
Given the probabilities of Stock A or B increasing, to find the likelihood that neither will happen, we need to consider their complements.
The complement for Stock A =1-0.54=0.46
The complement for Stock B =1-0.68=0.32
To calculate the probability of both events not occurring, we multiply these complements.
The probability that neither of these two events occurs is 0.46 x 0.32 = 0.1472

Answer:
C) cluster analysis
Explanation:
Regression analysis. This type of analysis identifies how two variables relate to each other, where one variable (X) is predetermined (dependent) and not random, whereas the second variable (U) is treated as independent and random. The unpredictability of U can arise from two factors: first, the measurement of U, which relies on X, can be subjected to errors; second, U could also be influenced by external factors that are outside of our control, in addition to its dependency on the corresponding X value. In such cases, it's necessary to discuss how the distribution of the random variable U correlates with each value of X. The primary objective of regression analysis is to establish a mathematical model that considers various factors affecting a physical process, making use of experimental data to assess its reliability. The least squares method is commonly applied to evaluate how well the mathematical model aligns with the experimental data.
Discriminant analysis involves a statistical method, commonly applied in pattern recognition and machine learning, to identify a linear combination of features that can delineate or categorize multiple classes or events. This linear combination can function as a classifier and is frequently used to condense data before classification occurs. LDA shares a close relationship with variance analysis (ANOVA) and regression analysis, which relate a dependent variable to other characteristics or dimensions in a linear fashion. However, discriminant analysis uses continuous independent variables to predict a qualitative dependent variable, whereas ANOVA pertains to qualitative independent variables with a continuous dependent variable.
Cluster analysis is aimed at the categorization of multiple items into groups based on shared features. The objects within a single cluster should demonstrate more similarity to each other than to those in different clusters. Clustering represents a key challenge in data analysis and is a frequently utilized method for statistical data evaluation. It finds applications in fields such as machine learning, image analysis, data retrieval, bioinformatics, data compression, and computer graphics.
One-way analysis of variance (ANOVA) assesses the significance of differences among three or more independent means within a normally distributed dataset. It focuses solely on comparing the average values across these groups; ANOVA results indicate significance if at least one of these comparisons shows significance. Its relevance lies in connection to regression analysis, where both dependent and independent variables are established.
