Construct a probability mass function (pmf) for x, the dollar amount won by a contestant in this game is 1/18.
What is a probability math example?
- Probability is the measurement of how likely something is to happen.
- As an example, since there is only one way to get a head and a total of two possible results, the likelihood of flipping a coin and getting heads is one in two. a tail or a head.
- We write P(heads) = 12 here. The four most popular approaches to probability are axiomatic, classical, empirical, and subjective.
from above total number of chips =4+6+5+2+1 =18
hence Probabilty of win 0 P(0)=4/18
P(1) =6/18
P(5) =5/18
P(10) =2/18
P(100)=1/18
x P(x) xP(x)
0 0.22 0.00
1 0.33 0.33
5 0.28 1.39
10 0.11 1.11
100 0.06 5.56
8.39
therefore expeted value =8.39

Domain of y = sqrt(x + 6) - 7 <br><br>
Finding domain is trying to check the following valid conditions <br>
<br>
condition 1: check for x such that the value in square root must greater or equal to 0 <br>(applicable here) <br>x + 6 >= 0<br>x > -6 ... this is the answer<br><br>
condition 2: check for x such that the divisor must not be zero <br>(not applicable here) <br><br>
condition 3(misc) : check some functions <br>for example ... log(0) is invalid...<br>
Answer:
=2+2*4
