Puan Aishah membeli 10 biji kek cawan. Antara kek cawan itu, 4 biji adalah berperisa coklat. Puan Aishah mengambil sebiji kek cawan secara rawak kepada anaknya. Hitung kebarangkalian anak Puan Aishah mendapat kek cawan yang bukan berperisa coklat? Puan Aishah bought 10 cupcakes. Among the cupcakes, 4 are chocolate-flavoured. Puan Aishah took a cupcake randomly to her child. Calculate the probability of Puan Aishah's child getting a cupcake that is not a chocolate-flavoured? A \( \frac{1}{5} \) (B) \( \frac{2}{5} \) C \( \frac{3}{5} \) D \( \frac{4}{5} \)

Kebarangkalian anak Puan Aishah mendapat kek cawan yang bukan berperisa coklat boleh dihitung dengan cara berikut. Puan Aishah mempunyai 10 biji kek cawan, di mana 4 biji adalah berperisa coklat, maka jumlah kek cawan yang bukan berperisa coklat adalah 10 - 4 = 6. Oleh itu, kebarangkalian untuk mendapatkan kek cawan yang bukan berperisa coklat adalah \( \frac{6}{10} \) atau \( \frac{3}{5} \). Jadi, jawapannya adalah C \( \frac{3}{5} \). Sekarang, mari kita lihat bagaimana kebarangkalian ini berfungsi dalam kehidupan seharian. Dalam situasi seperti ini, memahami kebarangkalian boleh membantu kita membuat keputusan lebih baik, seperti memilih makanan atau memahami risiko dalam pelaburan. Contoh yang menarik adalah permainan dadu; setiap kali kita melemparkan dadu, kita sebenarnya menggunakan prinsip kebarangkalian ini. Jadi, walau sekecil mana pun, kebarangkalian menjadikan setiap pilihan itu lebih menarik!

If events \( A \) and \( B \) are from the same sample space, and if \( P(A)=0.8 \) and \( P(B)=0.9 \), can events \( A \) and \( B \) be mutually exclusive? Explain. Choose the correct answer below. A. All probabilities are less than or equal to 1 and greater than or equal to 0 . If events are mutually exclusive, then \( P(A \cup B)=P(A)+P(B) \). Therefore, if \( A \) and \( B \) are mutually exclusive, \( P(A \cup \) \( B)=P(A)+P(B)=0.8+0.9=1.7 \), which is impossible. Therefore, events \( A \) and \( B \) are not mutually exclusive. B. All probabilities are less than or equal to 1 and greater than or equal to 0 . If events are mutually exclusive, then \( P(A \cup B)=P(A)+P(B) \). Therefore, if \( A \) and \( B \) are mutually exclusive, \( P(A \cup B)=P(A)+P(B)=0.8+0.9=0 \), which is possible. Therefore, events \( A \) and \( B \) are mutually exclusive. C. All probabilities are less than or equal to 1 and greater than or equal to 0 . If events are mutually exclusive, then \( P(A \cup B)=P(A)+P(B) \). Therefore, if \( A \) and \( B \) are mutually exclusive, \( P(A \cup B)=P(A)+P(B)=0.8+0.9=1 \), which is possible. Therefore, events \( A \) and \( B \) are mutually exclusive. D. All probabilities are less than or equal to 1 and greater than or equal to 0 . If events are mutually exclusive, then \( P(A \cup B)=P(A)+P(B) \). Therefore, if \( A \) and \( B \) are mutually exclusive, \( P(A \cup \) \( B)=P(A)+P(B)=0.8+0.9=1.7 \), which is possible. Therefore, events \( A \) and \( B \) are mutually exclusive. D. A
