That means the probability of an event can never be negative and cannot exceed 1. Here&#8217;s a breakdown of each option:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a. -0.25<\/strong>: This is a negative number, which is not a valid probability. Probabilities can only range from 0 (impossible event) to 1 (certain event). Hence, this is not a valid probability value.<\/li>\n\n\n\n<li><strong>b. 1\/4<\/strong>: This is a fraction that represents a probability value. Since 1\/4 equals 0.25, it lies between 0 and 1, making it a valid probability value. It means there is a 25% chance of an event occurring.<\/li>\n\n\n\n<li><strong>c. 37<\/strong>: This is a large number greater than 1. Probabilities cannot exceed 1, so this is not a valid probability value. A probability greater than 1 doesn&#8217;t make sense in the context of likelihood.<\/li>\n\n\n\n<li><strong>d. 1.3<\/strong>: This is a number greater than 1, which is not a valid probability value. Again, probabilities must lie between 0 and 1, so 1.3 is not valid.<\/li>\n\n\n\n<li><strong>e. 2 5\/9<\/strong>: This is an improper fraction greater than 1 (approximately 2.56), and like the others greater than 1, it is not a valid probability value.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Key Point:<\/h3>\n\n\n\n<p>Probabilities always fall within the range of 0 to 1. A probability of 0 indicates that an event will not occur, while a probability of 1 indicates that the event is certain to occur. Any number outside this range, whether negative or greater than 1, does not represent a valid probability.<\/p>\n\n\n\n<p>Thus, the only option that satisfies the condition of a valid probability is <strong>1\/4<\/strong>, or <strong>0.25<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of these is a probability value? a. -0.25 b. 1\/4 c. 37 d. 1.3 e. 2 5\/9 The correct answer and explanation is: The correct answer is b. 1\/4.
