Question

I would Like to double check my Answers.

An experiment consists of spinning a Spinner 3 times in succession and recording the number of the triangle on which it comes to rest, i.e. the number s 1,2,3 and 4. (For example, one possible outcome could be (2,1,3).)

Which of the following statements is/are true?

1) A: The sample space S is the set S={1,2,3,4}.

B: Consider the event E₁ "obtain at least two numbers that are the same". Then n(E₁)=16.

C: If P(E₂)=\frac{n(E_2)}{n(S)} and E₂ is the event "obtain all three numbers the same", the P(E₂)=\frac{1}{16}

1. Only A 2. Only B 3. Only C 4. Only A and B 5. Only B and C (I chose (1))


2) A The probability that two numbers are the same is greater than the probability that all the numbers are different.

B. The probability of not obtaining a 2 is the same as the probability of obtaining only the numbers 1,3 and 4.

C. The probability of scoring both 1 and 3 is \frac{9}{32}.

1. Only A 2.Only B 3.Only C 4. Only A and B 5. A,B and C (I chose (4))
