Answer:
A. The number of students that the club needs is at least (18).
Step-by-step explanation:
27 is the minimum requirement, so they need at <em>least</em><em> </em>18 people to meet said requirement. They can go over the limit.
The other answer comes into play if 27 was the <em>maximum</em><em> </em>that was allowed. Then they would need at most 18, because they can't admit any more people. They can't go over the limit.
Answer:
76 14/20
(76 7/10) simplified
Step-by-step explanation:
First we make the denominator of the fraction equal
82 15/20
24 16/20
18 15/20
We then subtract
82 15/20 - 24 16/20
81 35/20 - 24 16/20 =
57 19/20
Then we add
57 19/20 + 18 15/20=
76 14/20
(76 7/10) simplified
Let’s first see the probability of landing an even number. We have 6 sides, and 3 are labeled with an even number. So our chances of rolling a number cube are 3/6 (or 1/2 when simplified).
Next, the probability of rolling a number less then five is 4/6 (or 2/3 simplified), since we have 4 sides labeled with a number less than 5.
To compute two or more probabilities, we multiply them. In this case, the fractions already share the same denominator, 6 (because it’s a cube with 6 sides). So we get:
3/6 * 4/6
We then square 6, which is 36, and multiply 3 by 4, which is 12. This gives us 12/36, which is 1/3 in simplified form.
So there’s out answer: 1/3.

Note: If you have any queries related the answer please do comment. I would be very happy to resolve all your queries.
Firstly we will make PMF
For X=0, P=(4/5)^3=64/125
For X=1, P=C(3,1)*(1/5)*(4/5)^2=3*16/125=48/125
For X=2, P=C(3,2)*(1/5)^2*(4/5)=3*4/125=12/125
For X=3, P=C(3,3)*(1/5)^3=1/125
So,
E[X^2]=1*48/125+2^2*(12/125)+3^2/125=0.84
E[X]=48/125+12/125*2+1/125*3=0.6
So,
E[X]^2=0.36
