4. A multiple choice question has 5 possible answers. What are the odds in favor of guessing the right answer? (1 point)
A. 1:5
B. 4:1 ****
C. 1:4
D. 3:2
5. What are the odds of the spinner landing on red out of blue, green, and yellow? (1 point)
A. 4:1 ***
B. 2:2
C. 3:1
D. 1:3
question 5 confuses me. the question on my quiz is what are the odds AGAINST the spinner landing on red. wouldn't it be 3:4?
I'M STILL A TAD SLOW!!!
1:A(correct)
2:A (correct)
3:B (incorrect) complement is all the outcomes that are not the given outcome
4:B (correct)
5:technically isn't that 0? the odds of a spinner landing on red on a board comprising of only blue green and yellow is 0 (its impossible)
assuming that there should be red on the board: D (incorrect) there are 4 (random)outcomes, the odds of any one are 1:3.
Let's go through each question and check your answers:
1. P(number < 2) - The numbers less than 2 on a number cube are only 1. Since there are 6 equally likely outcomes (numbers 1 through 6), the probability of rolling a number less than 2 is 1 out of 6. So, the correct answer is A. 1/6.
2. P(number ≥ 3) - The numbers greater than or equal to 3 on a number cube are 3, 4, 5, and 6. There are four numbers that satisfy this condition. So, the probability of rolling a number greater than or equal to 3 is 4 out of 6. Simplifying this fraction gives us A. 4/6.
3. P(complement of 4) - The complement of 4 would include all the numbers except 4 on a number cube. So, there are five possible outcomes out of six for this event. The probability of the complement of 4 is 5 out of 6. Hence, the correct answer is B. 5/6.
4. The odds in favor of guessing the right answer in a multiple-choice question with 5 possible answers. In this case, there is only one correct answer out of the five options. So, the odds in favor of guessing the right answer are 1 out of 5. Thus, the correct answer is A. 1:5.
5. The odds of the spinner landing on red out of blue, green, and yellow depend on the number of possible outcomes in each category. Since only one category is specified, the odds would be the number of outcomes in favor (red) to the number of outcomes against (blue, green, and yellow). Since there is only one color that fulfills the condition, the odds of the spinner landing on red out of the three given options are 1 to 3. Hence, the correct answer is D. 1:3.
Your answers for the given probabilities are correct, well done!
