Assume that there are 2 trials.

X = 2 where X represents the number of successes.



Which probability matches the probability histogram?

Round the answer to one decimal place.



P(success)=0.2

P(success)=0.3

P(success)=0.7

P(success)=0.8

Answer:

P(success)=0.2 matches the probability histogram.

Step-by-step explanation:

Formula : [tex]P(X)=^nC_r p^r(1-p)^{n-r}[/tex]

Where X represents the number of successes.

p represents probability of success .

1-p represents probability of failure.

Now when X= 0 the  probability is 0.64 (Using histogram )

So, [tex]^2C_0 p^0(1-p)^{2}=0.64[/tex]

[tex](1-p)^{2}=0.64[/tex]

[tex](1-p)=\sqrt{0.64}[/tex]

[tex](1-p)=0.8[/tex]

[tex]1-0.8=p[/tex]

[tex]0.2=p[/tex]

So, the probability of success = 0.2

Hence P(success)=0.2 matches the probability histogram.

Answer:

P(success) = 0.2

This is the correct answer to this problem! I just took the test! Good luck!!
