Answer:
25/28 (Decimal: 0.892857 )
Branliest?
Please note that if you mult. 243 by 2/3, you get 162.
If you mult. 162 by 2/3, you get 108.
If you mult. 108 by 2/3, you get 72.
We can then safely conclude that the common ratio is 2/3.
Our last given set member was 72.
Mult. this by 2/3 to get the 5th member: 48.
Mult. this 48 by 2/3 to get the 6th member: 32.
Mult. this 32 by 2/3 to get the 7th and last desired member: 21 1/3

ANSWER
The missing probability is 0.15
EXPLANATION
From the given probability distribution table.
P(1)=0.30
P(2)=0.40
P(3)=0.15
P(4)=?
For for this to represent a probability distribution function,then the sum of all the probabilities must be equal to 1.
P(1)+P(2)+P(3)+P(4)=1
This implies that,
0.30+0.40+0.15+P(4)=1
0.85+P(4)=1
P(4)=1-0.85
P(4)=0.15
Therefore the missing probability is 0.15
11/20 = 55%
