There are 3 seventh- grade boys,4 seventh-grade girls, 5 eighth grade boys, and 8 eight grade girls that have parts in the schoo
l play. One cast member will have the responsibility of introducing the play. That cast member will be chosen randomly. What is the probability that the student introducing the play will be a boy?
Step-by-step explanation: 3 + 5 = 8 boys total 4 + 8 = 12 girls total 8 + 12 = 20 kids total. To find out the probability of randomly choosing a boy you have to do the number of boys over the total amount of kids (8/20) which will equal 40%.
Find the number in the hundredth place 4 and look one place to the right for the rounding digit 5. Round up if this number is greater than or equal to 5 and round down if it is less than 5
