The sample space of the experiment is the elements in the set
The sample space {Head, Tail} and there are 2 outcomes in the sample space
<h3>How to determine the sample space?</h3>
From the complete question, the experiment is a toss of a coin
A coin has a head and a tail.
So, the sample space (S) is:
S= {Head, Tail}
The number of outcomes in the above sample space is 2
Hence, the sample space {Head, Tail} and there are 2 outcomes in the sample space

You just have to put what you think on how much time you spend on the TV and stuff like for sleeping be like 300 min or 420 minutes you know,, and for homework you would be like 180 minutes
Adam can clean a room in 3 hours. If his sister Maria helps, they can clean it in 225 hours. How long will it take Maria to do the job alone?
2 2 = 12 Together time, 2 2 , needs to be converted to fraction 555
Adan:3,Maria:x,Total: 5 Clearlystatetimesforeachandtotal,usingxforMaria 12
1+1= 5 Usingreciprocals,addtheindividualtimesgivestotal 3 x 12
1
1(12x) + 1(12x) = 5(12x) 3 x 12
4x+12=5x −4x −4x 12=x It takes Maria 12 hours
Multiply each term by LCD of 12x
Reduce each fraction
Move variables to one side, subtracting 4x Our solution for x
Answer is - 12 hours
Answer:
a) We need to find p(x<68.15)
Standardize x to z, we have, z = (68.15-μ)/σ
=(68.15-57)/8.1
=1.38
Reading from standard normal tables,
p(z<1.38) =0.9162.
b) We need to find p(x>54.4)
Standardize x to z, we have, z = (54.4-μ)/σ
=(54.4-57)/8.1
=-0.32
Reading from standard normal tables,
p(z>-0.32) = 0.6255
