A card is chosen at random from a standard deck. Find the probability as a fraction that you will pick an ace.

P(ace)=

• 1/52

• 4/52

• 4/49

• 2/54

• 23/25

• 25/25

• 3/25

• don't worry about it because you are going to win

A group of students were asked about playing sports and instruments. If one of these students are choosen at random, find the correct probablity.

Match the probabilities.

• 24/50

• P(plays both instrument and sport)

• 22/50

• P(doesn't play a sport)

• 8/50

• P(plays a sport but not an instrument)

• 18/50

• P(instrument)

? 2) If a coin is tossed 25 times and lands on heads 20 times, what is the experimental probability that it will land on heads the next time?

What is the theoretical probability of rolling a 4 on a fair 6-sided cube?
