(Enter as a decimal) Suppose a family has three children . Find the probability they have at most one boy . (Enter as a decimal) 8 Different Combinations Consider the tossing of a pair of dice. Find the probability that the sum of the two die is 6 . (Round to the hundre

Find the probability the sum is greater than 6 . (Round to the hundre Referring to the table calculate the probability a randomly selected student received an A in the course. (Round Refer to the table. Given that receiving at least a C is passing the course, calculate the probability a student passe Refer to the table. Calculate the probability a student did not pass the course . (Round to the hundredths)

Question 11 Question 12 A single card is drawn from a standard deck of 52 playing cards . Find the probability the card is not a spade . A single card is drawn from a standard deck of 52 playing cards . Find the probability the card is not a king, quee

Question 13 Question 14 Remember An exam distribution has a normal distribution with mean 75 and standard deviation 10 . Calculate the probabili In this prob The 1st dev MCAT scores are normally distributed with an average score of 500.5 and a standard deviation of 10.5. Calculat

13 Cards that are Spades 52 - 13 = 39 Anwser so… = 39/52 = 0.75 The Total Amount of Cards is 52 12 Cards that are Kings, Queens, and Jacks 52 - 12 = 40 Anwser so… = 40/52 = 0.77 en, or jack . (Round to the hundredths)

The Total Amount of Cards is 52 2. We determine the the range for each Deviation: Anwser 68 r that 1st, 2nd, and 3rd Deviations are a percentage and each Deviation is just a segment of the data found in th ity that if the exam is given to a group of students that a student scores between 65 and 85 . (Write as a whole n blem, we draw and fill out the bell curve first w/ an average of 75 1. Given Standard Deviation = 10 = so from statring from 500.5 , we count by every point by 10 1st = 68% = 65 to 85 2nd = 95% = 55 to 95 3rd = 99.7 % = 45 to 105 viation ( 68% ) contains the scores bewteen 65 to 85 te the probability you get a score higher than 521.5 if you take the exam. (Don't include the percent sign.) Ex:) 1st Deviation = 68% = 68 of 100 , so the 1st Deviation is only 68% of the data found in the graph
