A binomial probability experiment is conducted with the given parameters. Compute the probability of x successes in the n independent trials of the experiment.
n = 15, p = 0.3, X = 3
P(3)=0
Answer:
[tex]P(x = 3) = 0.1700[/tex]
Explanation:
Given
[tex]n = 15[/tex]
[tex]p = 0.3[/tex]
Required
Determine P(x = 3)
This is calculated using:
[tex]P(x) = ^nC_xp^x(1-p)^{n-x}[/tex]
So, we have:
[tex]P(x = 3) = ^{15}C_3*0.3^3*(1-0.3)^{15-3}[/tex]
[tex]P(x = 3) = ^{15}C_3*0.3^3*(1-0.3)^{12}[/tex]
[tex]P(x = 3) = 455 *0.027*(0.7)^{12}[/tex]
[tex]P(x = 3) = 455 *0.027*0.0138412872[/tex]
[tex]P(x = 3) = 0.17004021325[/tex]
[tex]P(x = 3) = 0.1700[/tex]

Explanation:
Why are Neptune's years so long compared to Earth?
Answer:
Neptune’s axis of rotation is tilted 28 degrees with respect to the plane of its orbit around the Sun, which is similar to the axial tilts of Mars and Earth. This means that Neptune experiences seasons just like we do on Earth; however, since its year is so long, each of the four seasons lasts for over 40 years.
Explanation:
Answer:because the earth is closer to the sun
Answer for brainly, any trollers will be reported
Answer:
sorry i found this is the sat section and im laughing but i have your answer
Explanation:
7*7 is 49/2 is 24.5 so in simplest form it would be 25 for 4
and for 5 you should go with 60* 9/3 then multiply that by 90 since its your angle 90*180/7.5 your answer should be 36.3 and simplified to 36.0
60*3 is 180 hopw this helps
