am i correct.
Just to let you know, i am really bad at math:(
1)20% chance of spinning each one
2)= 40 40% *20=8
3)since there are 4 outcomes, theoretical = 25% my changed answer is 25%.28+22+34+16= 100 100 / 4 = 25%
4)my changed answer 3 15% of 20=3
5)20=2 50=5 2*5=10 A
6)24000 / 600 = 40
7)self explanatory
8)apple+apricot =6 10 all together 6/10=3/5
9)since a coin flip is random,it is a higher probability of the outcome to be H T H or B
10)since it says less than 5 and there is 6 sides on a dice all together, it is 5/6.
PLEASE CHECK
Don't listen to Math Match I got some wrong. For connexus users the anwsers are

5.A 50%
6.C The theoretical probability is equal to the experimental probability.
thank me
Smart/dummy is right he is 100%
thanks lala I really needed those otherwise I probably would have gotten 50%
bruh same day is correct for 2020 connexus students
lala is right i got 10/10! thank you so much lala i really needed help
i wasnt sure who to trust but im glad i trusted you
well actually she is right 6 is C so you is a dummy
ok here is for the quick check
1. C
2. C
3. A
4. B
5. A
This might be similar to someone's answers but this is what i got with 100%
peace!
-Stoopy
Tysm smarty/dummy he is right oh yeah i have a youtube channel its OwlThinker69 i will add it when im older
Lala for the win HIGH FIVE (smack) Thank you
"bruh same day" is right UwU tank chu
What about six questions
no #6 is c I just took the test according to lala
and got 100%
catlover, more like self-centered kid, lala is correct! it does not have 5 q's you should have read the post
Wait, with 'lala's awnsers I got 80%... I keep getting 80%.. huh. weird.. Any ways, thx lala
yet catlover is wrong and i just bombed the quick check
So apparently both the practice and the quick check have similar first questions, so 6 and 5. Lots of people get confused and i'll share the answers for quick check when I'm done
TYSM BRUH SAME DAY TYSM TYSM TYSM
lala is still correct to this day
@lala is correct for the Probability of independent events quiz

one sec let me take the test
Catlover isnt lying there are only five questions....
-.-" LOL no one is right for me- im in connexus- and litterly no one was right-------- .-. BEFORE YALL GO SAYING CAP i read through everything throughly. yall just need to understand theres differnts schools.... anyway- bye
i passed the quiz but i need the answers for the practice so if you have the answers please help
catlover is wrong cus i got 1/5 on mine
LANA IS WRONG STUPIDA
100% THANK U @stoopy
Color%C2%A0 red blue green yellow # of times spun 6 4 3 5%C2%A0 Use the table to answer the question. 1.%C2%A0%C2%A0What is the experimental probability of the spinner landing on red? %C2%A0(1%C2%A0point)
The experimental probability of the spinner landing on red is 0.3 or 30%.
Explanation:
There are 6 red sections out of a total of 18 sections on the spinner (since there are 4 colors and the spinner has 18 sections). To find the experimental probability, divide the number of times red was spun by the total number of spins:
6 red spins / 20 total spins = 0.3 or 30%
so in fractions, what is the probability?
The probability in fractions (as a ratio of favorable outcomes to total outcomes) of the spinner landing on red is 6/18, which can be simplified to 1/3.
yes 6 is 25 red cars
It was ccaab for me. I wasn't trying to lead anyone off track
LALA is RIGHT EXEPT FOR number 6, 6.B
The answers to the 5 question one in 2020 are
c
c
a
a
b
I can't say this is right for years from now but it is correct for right now in 2020
1. 0.6
2.40%
3. The experimental probability is 3% greater than the experimental probability.
4. 3 times
5.10 tickets
6.200 toys
7. Rolling two cube numbers
8. 3/5
9. The probabilities are the same.
10. 5/6
LALA NUMBER 6 IS B NOT C DUMMY
wait there are only 5 questions here
1. b
2. c
3. c
4. a
