) A card is drawn at random from a deck. What is the probability it is a red card?   What is the probability it is an ace?   What is the probability it is both red AND an ace?

On a shelf there are 60 novels and 20 poetry books. Person Achooses a book at random off the shelf and leaves with it. Shortly after, Person Bchooses another book at random. Calculate:a. The probability that the book selected by Person B is a novel?b. If it is known that Person B chose a novel: what is the probability that thebook selected by Person A was a poetry book?

American Airlines' flights from Denver to Atlanta are on time 90% of the time. Suppose thirteen flights are randomly selected, and the number on-time flights is recorded. 1. The probability that at least three flights are on time is?  2. The probability that at most twelve flights are on time is?  3. The probability that exactly two flights are on time is?

Cami plays softball. The table to the right shows the frequency of the number of hits she has per game. a) For a randomly selected game, what is the probability that she gets exactly 2 hits? b) What is the probability that she gets at most two hits c) What is the probability that she gets at least one hit? a) How is the probability that she gets exactly 2 hits found? O A. Subtract the probability of two hits from 1. ⒸB. Find the sum of the probabilities of no hits, one hit, and two hits. O C. Find the sum of the probabilities of three hits and four hits. O D. Divide the frequency of two hits by the total. The probability that she gets exactly two hits is (Simplify your answer.) b) What formula should be used to find the probability that she gets at most two hits? O A. P(at most two hits) = 1 - (P(three hits) + P(four hits)) O B. P(at most two hits) = P(no hits) + P(one hit) O C. P(at most two hits) = 1 - P(two hits) O D. P(at most two hits) = P(three hits) + P(four hits) The…

There are 6 balls in an urn: 1 red, 2 green, and 3 blue. An experiment has the following rules: i. If a red ball is drawn the experiment ends. ii. If a green ball is drawn, it is set aside and another ball is drawn. iii. If the blue ball is drawn, it is replaced and another ball is drawn. What is the probability that first ball was blue given that the second ball was blue?

A survey was done in regards to what type of animals are preferred as pets. Each respondent selected their top choice of animal for a pet. Respondents selected from: dog, cat, farret, fish, and bird.  After the survey was completed, 41% picked dog, 34% picked cat, 4% picked farret, 8% picked fish, and 13% picked bird.  Suppose three respondents were chosen at random. What is the probability that AT LEAST ONE of them picked dog?  Round the answer to 3 decimal places.
