If you roll a fair number cube four times you are more likely to get 2,3,1,6 than 6,6,6,6

Answer:

its  is incorrect.

Step-by-step explanation:

Each time you roll the dice, you have a 1 in 6 shot in getting any number. Rolling a 6 does not lower the odds of rolling another 6. Therefore the odds of both of these are (1/6)^4.

This does however change if you are allowed to roll these numbers in any order. In that case, the first batch would be easier.

Answer:

No

Step-by-step explanation:

Every time you roll the dice, there is the same probability of rolling any number (1/6)

Simply compute (1/6)^4, which can also be written as (1/6)*(1/6)*(1/6)*(1/6)

this equals 1/1296.

The probability of rolling any given number is the same, so the probability of rolling any sequence of four numbers is the same.

In a certain city of several million people, 7.7% of the adults are unemployed. If a random sample of 300 adults in this city is
Lilit [14]

Answer: 0.2643

Step-by-step explanation:

Given : The proportion of  adults are unemployed : p=0.077

The sample size = 300

By suing normal approximation to the binomial , we have

\mu=np=300\times0.077=23.1

\sigma=\sqrt{np(1-p)}=\sqrt{300\times0.077(1-0.077)}\\\\=4.61749932323\approx4.62

Now, using formula z=\dfrac{x-\mu}{\sigma}, the z-value corresponding to 26 will be :-

z=\dfrac{26-23.1}{4.62}\approx0.63

Using standard distribution table for z , we have

P-value=P(z\geq0.63)=1-P(z

=1-0.7356527=0.2643473\approx0.2643

Hence, the probability that at least 26 in the sample are unemployed  =0.2643
