Given that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring, choose all that are correct.
Responses
A 1 indicates an impossible event
B 0 indicates a certain event
C 0.5 indicates equally likely to occur or not occur
D 0.25 indicates an unlikely event
E 0.75 indicates an unlikely event
The probability that the cup will land open end down is:
A - 37
This is because the cup landed open end up 63 times out of 100 tosses, which means it landed open end down 37 times out of 100 tosses. So the probability of the cup landing open end down is 37/100 or 0.37.
Therefore, the correct answer is option A - 37.
B - 0 indicates a certain event
C - 0.5 indicates equally likely to occur or not occur
D - 0.25 indicates an unlikely event
E - 0.75 indicates a likely event
but E. saying 0.75 indicates unlikely event...
I apologize for the error in my previous response. The correct answer is:
B - 0 indicates a certain event
C - 0.5 indicates equally likely to occur or not occur
D - 0.25 indicates an unlikely event
E - 0.75 indicates a likely event
Thank you for bringing this to my attention.
unless it was some typo on their end
Yes, it's possible that there was a typo or error in the original question. However, given the definitions of probability and the given options, it is clear that 0.75 indicates a likely event, not an unlikely one. So, if there was indeed an error, it should be corrected.
A bag contains 1 yellow ball and 9 red balls. A ball is chosen at random from the bag. What is the BEST answer for the probability of drawing the yellow ball?
Responses
A certain
B unlikely
C impossible
D very likely
The BEST answer for the probability of drawing the yellow ball is:
A - certain
This is because there is a guaranteed chance of selecting the one yellow ball from the bag.
i get mixed up on these questions
Probability questions can be confusing at times, but with enough practice, you will become more confident in your ability to solve them. Here's a breakdown of this particular question and how to approach it:
There are 10 balls in the bag, one of which is yellow and the other nine are red. Since one ball must be selected and there is only one yellow ball in the bag, the probability of drawing the yellow ball is 1 out of 10 or 1/10. This fraction reduces to 0.1 or 10%.
In this case, the probability of drawing the yellow ball is certain because there is a guaranteed chance of selecting it.
I hope this explanation helps you better understand how to approach probability questions.
