A six-sided number cube with faces numbered 1, 2, 3, 4, 5, and 6 is rolled. Which events are mutually exclusive? A. rolling a 4, rolling a prime number B. rolling a 3, rolling a prime number C. rolling a 2, rolling an even number D. rolling a 5, rolling an odd number
i give medals! please help me!!!!!
How do you understand "mutually exclusive events" (in this question) ?
once your done will you help me with mine?
well i know that mutually exclusive events are like probability, but when i did it like that i got he wrong answer. let me see if i can show you my problem through screenshot. if not then iono what to do my computer sucks sometimes
OK, I am just going to explain this really quick . you are rolling the cube ONCE . Lets take choice A. if you rolled 4, you rolled a prime number. In other words 4 is a prime number. Is that true or false ?
I have no idea exactly what I did and what im doing and what im doing wrong, but I reread the lesson and it clicked (again) but when it came to the assessment it was asking questions that I didn't learn in the lesson
false i think... because 2 can multiply itself by itself to make 4
2•2=4
Yes, so rolling a 4 and rolling a four a mutually exclusive events - they exclude each other, because if you rolled 4 you didn't roll a prime number, and visa versa.
ok1 i get it now! so the answer would be whatever the number is- like rolling a four and rolling a composite number!
Just making it more easier, ik you get it ;) A. 4 is NOT a prime number B. 3 is a prime number C. 2 is an even number D. 5 is an odd number
ok now i don't because that made it harder. youre basically telling me there's 3 answers
well A. is out, but what about the others?
No, I am telling that B C and D are true and A is not,.
ohhh
so should I go with the one that is more likely probability wise to be correct? then that would be b... right?
because only 3 and 5 are prime numbers on a di
No, you are asked - in which of the choices the two event exclude each other? only in A, because only in A youcan roll either 4 or a prime number, since they are different things. in the rest of the choices the 2 things (like in B rolling 3 and a prime) are same.
exactly @SolomonZelman
ok... after you gave me those answers up there i got lost like someone got lost in the sahara desert
OK, do you get it now though ?
so to sum it up i really never understood it and I still don't because i never came to a clear answer. I really appreciate your time and help and you spending your nerves on my tiny brain but then what would the answer be and why?
if i know that then using the help you gave me then I can probably piece up some understanding ^3^
sorry that was probably rude...
Answer the question. in which of the choices (A,B,C and D) are the 2 events contradicting each other ?
a
Yes, so A is therefore the answer.
OH NOW I GET IT IM SO SORRY MUTUALLY ExClUsIvE!!!!!!!!!! I'm so stupid!
and slow because after all this time i remember what exclusive means... ^v^ sorrys...
It's alright ;) ...anyone has problems...
lol heh heh......
have a good one.
you too @SolomonZelman
