If a coin has been altered so that the probability of heads coming up is 3/10, then the probability of tails coming up is also 3
soldier1979 [14.2K]
False. In a coin, there are 2 possible out comes i.e. a head and a tail. if p is the probability of one side coming up, then the probability of the other side comin up will be q = 1 - p.

Therefore, if the probability of head coming up is 3/10, the probability of tail coming up will be 1 - 3/10 = 7/10.

G a survey of property owners' opinions about a street-widening project was taken to determine if owners' opinions were related
Naily [24]

Answer:

The expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.

Step-by-step explanation:

The data provided is:

                                                   Opinion    

Front Footage   For       Undecided Against    Total

Under 45 feet    12                4              4              20

  45-120 feet           35                5             30      70

Over 120 feet     3                2              5              10

       Total           50                11             39    100

The formula to compute the expected frequency is:

E(X)=\frac{\text{Row Total}\times \text{Column Total}}{\text{TOTAL}}

Compute the expected frequency for people against the project and who have over 120 feet of property foot frontage as follows:

E(X)=\frac{\text{Row Total}\times \text{Column Total}}{\text{TOTAL}}

E(5)=\frac{10\times 39}{100}=\frac{39}{10}=3.9

Thus, the expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.
