Acoin was flipped 150 times. the results of the experiment are shown in the following table: heads tails 90 60 which of the following best describes the experimental probability of getting heads?
options:
it is 10% higher than the theoretical probability.
it is 10% lower than the theoretical probability
it is equal to the theoretical probability for this data
the experimental probability cannot be concluded from the data in the table

I personaly thisnk its A correct me if im wrong

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

b and c
