A bag has 14 marbles, all identical except for their color. There are 6 red marbles, 5 blue marbles, and 3 yellow marbles. If you draw two marbles from the bag WITHOUT replacement, find the following probabilities: **LEAVE ALL ANSWERS AS FRACTIONS** 15 a.) P(RR)= 91 30 b.) P(RB)= 91 X 18 C.) P(RY)= 91 d.) P(BR) = 10 e.) P(BB)= 91 30 91 15 f.) P(BY)= 91 g.) P(YR) h.) P(YB) - W 18 91 61 15 91 L.) P(YY)- 91 X X > X X X
Students conducted a a survey as part of a Statistics project to determine if younger adults are more likely to have tattoos. The results are listed in the two-way table below: Age 18-29 Age 30-50 Column Totals At least 1 tattoo No tattoo Row totals 172 337 62 444 234 781 What is the Probability that a person chosen at random: **LEAVE ALL ANSWERS AS FRACTIONS** a.) Has at least 1 tattoo? = 234 1015 b.) is between 30-50 years old? = 506 1015 c.) Is Age 18-29 AND has No tattoo = 509 506 1015 337 1015 d.) Has at least 1 tattoo GIVEN they are between 30-50 years old?= 86 e.) is between 18-29 years old GIVEN they have at least 1 tattoo? = 117 f.) is between 18-29 years old OR has No tattoo? = 31 235 953 1015
