12 data management. also the last answer is enough for me.

Part A: Knowledge and Understanding 1. The theoretical probability can change depending on how many trials you attempt. a) True b) False 2. Drawing 2 spades in a row would be an example of dependent events. a) True b) False 3. If A1, A2, ..., As are all of the events in S, then P(A1) + P(A2) + ... + P(As) is equal to... a) n(S) b ) 0 c) 1 d) impossible to determine 4. A sample space only has events A, B and C. If P(A) = 0.3, then P(B) is equivalent to which of the following? a) 30% b) 35% c) 70% d) not enough information to determine 5. To calculate a sequence of independent events, which of the following operations is used? a) addition b) subtraction c) multiplication d) division e) none of these 6. Consider the events of drawing a spade and rolling a 5 on a 6 sided die. These events are... a) independent events. b) dependent events. c) neither of these. 7. A car comes in 4 colours, 3 styles and 2 engine options. The number of different cars is: 8. Given S = {A, B}, n(A) = 30 and n(S) = 70, what is the value of n(C)? 9. Using a d20, what is the probability of rolling a 5 and then a 9? 10. Consider the tree diagram for the following outfits that Sanjana could wear. How many different branches would be drawn in the tree diagram? There are 5 different shirts, 4 pants that would match and 3 sweaters that match which she could wear
