A box of jerseys for a pick-up game of basketball contains 9 extra-large jerseys, 6 large jerseys, and 5 medium jerseys. If you

Answer:

1/114 or 0.008772

Step-by-step explanation:

I am not very sure, my answer seems unlikely, but here's what I think:

There are 20 jerseys in the box to begin with, and 5 medium jerseys that you can have.

Therefore, the probability of you randomly grabbing a medium sized jersey is 5/20 or 1/4.

After taking out one medium sized jersey, there are 19 jerseys in the box and 4 medium jerseys you can pick from.

The probability of you randomly grabbing a medium sized jersey is 4/19.

After taking out another medium sized jersey, there are 18 jerseys left in the box and 3 medium jerseys you can pick from.

The probability of you randomly grabbing a medium sized jersey is 3/18.

To get the answer, you do 1/4 * 4/19 * 3/18, and get 1/114, or 0.00877192982.

If you round that to the nearest millionth, it's 0.008772

Don't judge me, it might not be correct.

never [62]

Answer:

$P(n>55)=0.1357$

Step-by-step explanation:

From the question we are told that:

Sample size n=100

Sample space n'=36

Generally the equation for the mean number of times odds appears is mathematically given by

$\=x_o=hp$

$\=x_o=100*0.5$

$\=x_o=50$

Generally the equation for standard deviation is mathematically given by

$\sigma=(hp(1-p))^{1/2}\\\sigma=(50(0.5))^{1/2}$

$\sigma=5$

Therefore probability to make wrong decision P(n>55)

$P(n>55)=1-P(z55)=1-P(z55)=1-0.86$

$P(n>55)=0.1357$

the maximum load of elevator is 480 pounds. Assuming that the average mass of student is 45 pounds, and m represents the number

yaroslaw [1]

We can use the equation 45m < 481

we can replace m to see where it caps.

and the cap is 10.

we can replace m to check our work

45(10) < 481

450 < 481

if you add another student, it would go over the limit.

hope this helps :D
