So, all 8 numbers added up would equal 80. and all 6 numbers added up would equal 72. The subtract them. 80-72 is 8. Then divide by 2 because there are 2 numbers. 8/2 is 4. (4 is your answer)
Answer:
a)

b) 0.476
c) 0.667
Step-by-step explanation:
We are given the following in the question:
Y = the number of forms required of the next applicant.
Y: 1, 2, 3, 4, 5, 6
The probability is given by:

a) Property of discrete probability distribution:

b) at most four forms are required

c) probability that between two and five forms (inclusive) are required

Lets first convert everything to inches.
6 feet= 12*6 = 72 + 10 = 82 inches
8 feet= 12*8 = 96+9 = 105 inches
Now add!
82+105 = 187
Now convert them back to feet.
187/12 = 15 feet
12*15 = 180
187 - 180 = 7 inches
15 feet. 7 inches.
Final answer: B. 15 ft. 7 in.
The answer is 67.93939393939394
