Answer:
1.75a+8b
Step-by-step explanation:
Question = 0.75a + 10b + a - 2b
First collect like terms 0.75a + a + 10b - 2b
= 1.75a + 8b
what are <u>like</u><u> </u><u>terms</u> : they are terms with the same variable and the same exponent. example: 9xy and -6xy etc.......

Answer:
a)
b) 


And we have the following table:
X | 0 | 1 | 2
P(X) | 0.25 | 0.5 | 0.25
Step-by-step explanation:
Let's define first some notation
H= represent a head for the coin tossed
T= represent tails for the coin tossed
We are going to toss a coin 2 times so then the size of the sample size is 
a. What is the sample space for this chance experiment?
The sampling space on this case is given by:
b. For this chance experiment, give the probability distribution for the random variable of the total number of heads observed.
The possible values for the number of heads are X=0,1,2. If we assume a fair coin then the probability of obtain heads is the same probability of obtain tails and we can find the distribution like this:



And we have the following table:
X | 0 | 1 | 2
P(X) | 0.25 | 0.5 | 0.25
