@zaasmi said in A bag contains 10 white, 2 orange and 3 black balls. What is the probability of black balls?: A bag contains 10 white, 2 orange and 3 black balls. What is the probability of black balls? 3/15 Wrong To calculate the probability of drawing a black ball, we use the probability formula: Probability = Number of favorable outcomes/Total number of outcomes Here: • The number of black balls (favorable outcomes) = 3 • The total number of balls (white + orange + black) = 10 white + 2 orange + 3 black = 15 So, the probability of drawing a black ball is: 3/15=1/5 Thus, the probability of drawing a black ball is 1/5.

@zaasmi said in A bag contains 12 red balls and 12 blue balls. A ball is drawn at random. The probability that ball drawn is red isf: A bag contains 12 red balls and 12 blue balls. A ball is drawn at random. The probability that ball drawn is red isf 1/2P (A union qual to:? To find the probability that a randomly drawn ball is red, we use the basic probability formula:  Probability = Number of favorable outcomes/Total number of outcomes Here: • The number of red balls (favorable outcomes) = 12 • The total number of balls (red + blue) = 12 red + 12 blue = 24 So, the probability of drawing a red ball is:  Probability = 12/24 = 1/2 Thus, the probability that the ball drawn is red is 1/2 or 50%.

@zaasmi said in STA301 - Quiz Solution and Discussion: In a Box and Whisker plot, if the median line is closer to the left of the box then distribution will be: STA301 In a Box and Whisker plot, if the median line (which represents the second quartile, or Q2) is closer to the left of the box, it indicates that the data is positively skewed (also known as right-skewed). This means: • The majority of the data points are concentrated on the lower end of the range. • There is a longer tail towards the higher values (right side of the distribution). • The right side of the box (between Q2 and Q3) is wider than the left side (between Q1 and Q2), indicating that the upper half of the data is more spread out. Thus, the distribution will be positively skewed.
