If six people decide to come to a basketball game, but three of them are only 2/5 sure that they will stay for the entire time (

exis [7]

Answer:

the probability that at the end, at least 5 people stayed the entire time = 0.352

Step-by-step explanation:

From the question, 3 of the people are sure to stay the whole time. So, we'll deduct 3 from 6.which leaves us with 3 that are only 2/5 or 0.4 sure that they will stay the whole time.

Thus, what we need to compute to fulfill the probability that at the end, at least 5 people stayed the entire time of which we know 3 will stay, so for the remaining 3,we'll compute;

P[≥2] which is x~bin(3,0.4)

Thus;

P(≥2) = (C(3,2) x 0.4² x 0.6) + (C(3,3) x 0.4³)

P(≥2) = 0.288 + 0.064

P(≥2) = 0.352

What’s this question

yKpoI14uk [10]

<h3>Hm ok, so the correct answer here would be (0,3) and heres why:</h3>

If the y would be equal to 0, everything would then just depend if you add or subtract the x:

$y-x=-3\\\\y+x=3\\\\y= 0\\x=3\\\\then:\\\\0-3=3\\and\\0+3=3$

Now the first answer could be correct for:

$y-x=-3\\because\ if\\\\y=-3 \ and \ x=0 \ then\\-3-0=-3$

However, this answer is not correct for the other equation. the same true for all the other answers except (0,3)
