Create a bar graph by dragging the sliders on the horizontal axis to represent the probability distribution.

probability of an event E,

P(E)=No. of favourable outcomes total no. of outcomes

P(1)=420=15=0.20

P(2)=620=310=0.30

P(3)=220=110=0.10

P(4)=620=310=0.30

P(5)=220=110=0.10

Step-by-step explanation:

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
