A 1/3
B 5/12
C 2/3
D 5/6 <----------------------

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.

Smart/dummy is right he is 100%

Answer 36

Tysm smarty/dummy he is right oh yeah i have a youtube channel its OwlThinker69 i will add it when im older

Answer 37

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)

Answer 38

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%

Answer 39

so in fractions, what is the probability?

Answer 40

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.
