Abstract
The probability is very closely related to everyday life that includes a probabilistic situation. This situation contains an element of uncertainty when someone is thinking about a problem that has various possibilities or consists of a part of luck, then that person is thinking probabilistically. The purpose of this study is to analyze the mathematical probability thinking skills of senior high school students in the response aspect with gender and mathematical abilities. This type of research is a qualitative descriptive study based on five stages, namely (1) natural design, (2) descriptive data, (3) attention, (4) data processing, and (5) the main focus of research. The research was conducted at Senior High School in Jayapura, Indonesia. The research subjects were students of class XI Science. The research instrument consisted of mathematical ability test sheets, probability problem-solving tasks, interviews. The results of the investigation show that the profile of male students' probabilistic thinking on mathematical abilities in solving probability problems includes providing statistical responses in solving probability. Issue is related to the sample space (representatives formation) because it uses a combination to calculate the number of members of the sample space by providing the right reasons. Meanwhile, for women, the profile of probabilistic thinking is using several strategies in solving probability problems related to the sample space (representatives formation). Based on the investigation of the results shows that there are differences in mathematical ability between male and female students probability of problem-solving.
Highlights
Mathematics is a universal language that allows people to think record and communicate ideas about elements and quantities at all times
This section will describe the results of data analysis in the first and second categories which reveal the types of strategies used by SLT when solving problem probability problems
From the results of data analysis in the first and second categories, it revealed that the strategy category used a combination to calculate the many kinds of representatives that could be forming consisting of three sub-categories, namely: using combinations, counting the many different types of representative Group A could create, and measuring the many different kinds of representatives Group B could form. It showed that SLT used a combination to solve this probability problem (W1LT(1)006)
Summary
Mathematics is a universal language that allows people to think record and communicate ideas about elements and quantities at all times. The value of thinking skills will have an impact on life because it is very dependent on human thinking skills to survive and adapt to the environment. Various aspects required to help both of these thinking skills, one of which is the mathematical aspects. Mathematical skills are required to help activities, whether in the living system or the education system. The role of mathematics has a significant impact on the development of the mindset of an individual or an student. The value of mathematics is strengthened by the activism and content obtained. One of the mathematical intelligence needed by a student is probabilistic thinking [1]
