A box contains 1.0 red chips, 20.bluechips, and 30 green chips. ll5 chrps are orawn lrom the box, find the probability of drawin
alexira [117]

Answer:

Step-by-step explanation:

Let S be the sample space of an experiment and E is an event associated with the experiment.

Let n(S) and n(E) denote the number of element in S and E.

P(E) is the probability of an event E

The number of elements on the sample space ;

n(S) = n(r) + n(b) + n(g) = 10 + 20 + 30 = 60

Hence, the event of drawing 5chips from the box n(S) = C(60,5)

A) probability of drawing 5chips from the box which are all blue ;

P(E) = n(E) / n(S) = 20C5 x 40C0 / 60C5 = 0.0028

by combination method ; nCr = n!/r!(n - r)!

B) the probability of drawing the indicated chips at least 1 green ;

Application of the binomial formula comes in ; nCr x p^r x q^n-r

= P(E) = 1 - p(x <1) = 1 - po = 1 - 30C0 x 30C5 / 60C5

= 0.9739

C)  the probability of drawing the indicated chips at most 1 red;

P(E) = p(no red) + p(one red)

= 10C0 x 50C5 + 10C1 x 50C4 / 60C5

= 0.8096

Hello! This is my first question ever. I am in AP Calculus and am working on a redo. I know the correct answer but don't know ho
Kipish [7]
Since \Delta x=\dfrac{b-a}n, and you have a corresponding term in the given Riemann sum of \dfrac5n, you know the integral is being taken over an interval of length 5, so you can omit the second choice.

Next, f(a+i\Delta x) corresponds to a=3 with \Delta x=\dfrac5n. The fact that a=3 alone tells you that the interval of integration starts at 3, and since we know the interval has length 5, that leaves the first choice as the correct answer.
