in an experiment, college students were given either four quarters or a $1 bill and they could either keep the money or spend it on gum. the results are summarized in the table. complete parts (a) through (c) below.\n\n| |purchased gum|kept the money|\n|--|--|--|\n|students given four quarters|34|14|\n|students given a $1 bill|16|25|\n\n a. find the probability of randomly selecting a student who spent the money, given that the student was given four quarters.\n\nthe probability is \n(round to three decimal places as needed.)
Answer
Explanation:
Step1: Identify relevant numbers
The number of students given four - quarters who spent the money (purchased gum) is 34, and the total number of students given four - quarters is (34 + 14=48).
Step2: Calculate the conditional probability
The formula for conditional probability (P(A|B)=\frac{n(A\cap B)}{n(B)}). Here, (A) is the event of spending the money and (B) is the event of being given four - quarters. So the probability (P=\frac{34}{48}).
