1. A special deck of cards has 3 bluecards, and 7 orange cards. The blue cards are numbered 1, 2, and 3. The orange cards are numbered 1, 2, 3, 4, 5, 6 and 7. The cards are well shuffled and you randomly draw one card.

B = card drawn is blue O = card drawn is odd-numbered

a. How many elements are there in the sample space?

b.P(B) =

2. A classic deck of cards is made up of 52 cards, 26 are black, 26 are red. Each color is split into two suits of 13 cards each (clubs and spades are black and hearts and diamonds are red). Each suit is split into 13 individual cards (Ace, 2-10, Jack, Queen, and King). If you select a card at random, what is the probability of getting: (Round to 4 decimal places where possible) a) A 4 of Hearts? b) A Spade or Heart? c) A number smaller than 3 (counting the ace as a 1)?

3. A geneticist conducts an experiment with peas, one sample of offspring consisted of 459 green peas and 168 yellow peas. Based on these results, estimate the probability of getting an offspring pea that is green.

Report the answer as a percent rounded totwo decimal place accuracy. Probability = % Is the result reasonably close to the value of 3/4 that was expected?

4.Use the spinner below to find the probability of getting the following after 1 spin.
