You decided to throw a fair die four times.

Mathematics
1 answer:
Finger [1]2 years ago
7 0

Answer:

If all you care about is whether you roll 2 or not, you get a Binomial distribution with an individual success probability 1/6. The probability of rolling 2 at least two times, is the same as the probability of not rolling 2 at zero or one time.

the answer is, 1 - bin(k=0, n=4, r=1/6) - bin(k=1, n=4, r=1/6). This evaluates to about 13%, just like your result (you just computed all three outcomes satisfying the proposition rather than the two that didn’t).

Step-by-step explanation:

Half the marbles in a bag are red, 1/6 of the marbles are blue, and the remaining 8 marbles are white how many total marbles are
Gemiola [76]

Hey there! I'm happy to help!

Let's represent the total number of marbles with the variable t. We have the following information.

1/2t+1/6t+8=t (1/2 of total are red, 1/6 of total are blue, 8 are white, add them up to get total)

Now, we solve for t.

1/2t+1/6t+8=t

We combine like terms.

2/3t+8=t

We subtract t from both sides.

-1/3t+8=0

We subtract 8 from both sides.

-1/3t=-8

We divide both sides by -1/3.

t=24

Therefore, there ae 24 total marbles in the bag.

Have a wonderful day! :D

Multiply the binomials: <br><br> (a-2) • (a-8)
umka21 [38]

Answer:

a^2 -10a +16

Step-by-step explanation:

(a-2) • (a-8)

FOIL

first a*a = a^2

outer: a * -8 = -8a

inner: -2 *a = -2a

last: -2 *-8 = 16

Add them together

a^2 -8a -2a+16

Combine like terms

a^2 -10a +16
