She randomly divides one grove's trees into three groups. One group is the control with no treatment for blight. She prunes the second group to remove the limbs showing blight after the spring rains. She prunes the third group as well and also sprays them with an antibiotic. Vanessa monitors the trees for ve years after the start of the experiment. The table shows the outcomes, or the counts of how long the trees in each group lived.

Give your answer as a decimal, precise to three decimal places. Probability = Incorrect This Venn diagram shows the makeup of attendees at a college social event sponsored by the French Club. The event is open to all students. There are 40 students at the party who are fluent in Attendees at French Club party French. There are 55 students at the party who are fluent in English. There are 135 students at the party. Use the Venn diagram and given information to find the probability that a student selected at random is fluent in both French and English. Assume the chance of being selected is the same for each student. Express your answer as a percentage rounded to one decimal place. 29 14 Fluent English Fluent French speakers speakers Probability = % IncorrectMaggie is practicing her penalty kicks for her upcoming soccer game.
