Q7.(A=4) Expand and simplify. a) (p) b) (3m+) Q8 (K=3, C= 3)) Mr. Dobson's tie rack is shown below. Counting and Probability What is the probability that Mr. Dobson randomly selects a) a solid blue tie or a polka dot tie? b) a striped tie or a solid coloured tie? c) a solid black tie or a striped tie? Q9 (T=2, A=2) Solve for n. a) P=110 a) b) P(n, 3)=5! b) Q1. (T=2, C=1) The experimental probability of randomly choosing a male from a litter of puppies is. If there are 6 female puppies in the litter, how many males are there? Q2. (T=3, C=1) A spinner has four colours: red, yellow, green, and purple. The experimental probability of spinning a red is 0.2, of spinning a yellow is 0.3, and of spinning a green is 0.4. If the spinner was spun 30 times, how many times did it lands on purple Q3. (K=4, C=1) a) How many arrangements are there of the letters in the word COMPUTER? b) How many of them begin with a consonant? a) b) Q4. (A=4, C=2) Determine the number of paths that spell PASCAL. Can combinations be used to solve each question? a) A CCCC AAAAA LLLLLL b) S C A A s L 40 b) Q5. (T=3, C=1) Refer to Rolly's James Bond movie collection Suppose Rolly randomly picks a movie to watch, and then randomly picks a second movie without putting the first movie back on the shelf. Determine the probability of each of the following scenarios: a) Rolly will watch a Connery movie followed by a Moore movie. b) Rolly will watch two consecutive Dalton movies. c) Rolly will watch three consecutive Craig movies. Actor Sean Connery George Lazenby Roger Moore Timothy Dalton Number of Movies 6 1 7 2 Pierce Brosnan Daniel Craig 4 2 Q6. (K=2, C=1) A bag contains two apples, one orange, and two peaches. Suppose Jelena reaches in and chooses a piece of fruit at random, and then selects another piece of fruit without replacing the first one. What is the probability that she will choose two peaches?
