Answer:
0.0728177272
Step-by-step explanation:
Given :
Number of flips = 80
Probability of landing on tail at most 33 times ;
Probability of landing on tail on any given flip = 1 / 2 = 0.5
This a binomial probability problem:
Hence ;
P(x ≤ 33) = p(x=0) + p(x=1) +... + p(x = 33)
Using a binomial probability calculator :
P(x ≤ 33) = 0.0728177272
Answer: 
<u>Step-by-step explanation:</u>
The probability of NOT getting a 4 means the probability of getting a 1, 2, 3, 5, or 6 which is 5 out of 6 = 
The probability of getting a 4 is 1 out of 6 = 
The probability of getting a 4 only on the last roll is:
NOT 4 and NOT 4 and NOT 4 and Yes 4

Mean = (7+3+10+13+x)/5
(7+3+10+13+x)/5 = 8
(7+3+10+13+x) = 40
x = 40-7-3-10-13 =7
