In a large bag of marbles, 20% of them are red. A child chooses 4 marbles from this bag. If the child chooses the marbles at ran
lubasha [3.4K]

Answer:

0.0256

Step-by-step explanation:

Assuming a binomial model, with probability of success (getting a red marble) p = 0.20. The probability of obtaining 'k' successes in 'n' trials is:

P(x=k)=\frac{n!}{(n-k)!k!}*p^k*(1-p)^{n-k}

For k = 3 red marbles in n = 4 trials:

P(x=3)=\frac{4!}{(4-3)!3!}*0.20^3*(1-p)^{4-3}\\P(x=3)=4*0.20^3*0.8\\P(x=3) = 0.0256

The probability that the child gets exactly three red marbles is 0.0256.

the table shows the melting points of various elements is the absolute value of the melting point of neon greater than or less t
r-ruslan [8.4K]

The  absolute value of the melting point of neon greater than the absolute value of the melting point of hydrogen.

<u>Step-by-step explanation:</u>

In positive numbers, when the number gets larger then it is considered to be the greatest number.

for example: 20 > 5.

Meanwhile, For negative numbers, when the number gets larger then it is considered to be the smallest.

For example: -21 > - 40.

From the given table, we are given with the values of Melting point:

Hydrogen= -259.

Neon = -248.

Oxygen = -218.

We have to compare the melting points of hydrogen and neon,

⇒ - 248 > - 259.

Thus the melting point of the neon is greater than the melting point of the hydrogen.
