You turn the cards the face down and shuffle. Then you turn one card face up. Express the probability of each event as a fraction in simplest form. 1. heart 1 plus sign 1 star 1 triangle 1 not circle 5 not star 3 circle or plus sign 1 not heart or star 7 not triangle or star 2 The chart on the below shows the months in which each of the 24 students in Mrs. Maxwell's class were born. Each student's name is written on a slip of paper and placed into a jar. If Mrs. Maxwell picked the name of one student from the jar, what would be the probability of each event listed below? Express the probability of each event as a fraction in simplest form. 10. a student born in January - March 1 a student born in July - December 5 a student born in January - June 7 a student born in April - June 1 a student not born in April - June 2 a student not born in July - September 7 There are 24 marbles in the jar below.
