Answer:
14/33
Step-by-step explanation:
The total amount of beads is 8+4 = 12. 8 of these are black beads, so that is what we want, so 8/12 or 2/3. For the second one, one black bead is already taken so 8-1 = 7 are left and for the total 12 - 1 = 11 are left, so 7/11. Multiply this by 2/3 and we get 14/33.
Well i think you are suppose to explain how OR WHAT THE CHANGE IN DECREASE Is.
Hope i helped

There is 70.7% chance that at least one but at most two adults in the sample believes in the ghost

There will be one adult out of three we expect to believe in the ghost
Step-by-step explanation:
The probability distribution is constructed using binomial distribution.
We have to construct the probability distribution of the number adults believe in ghosts out of three adults. so,
x=0,1,2,3
n=3
p=probability of adults believe in ghosts=0.38
The binomial distribution formula
nCxp^xq^n-x=3cx0.38^x0.62^3-x
is computed for x=0,1,2,3 and the results depicts the probability distribution of the number adults believe in ghosts out of three adults.
x P(X)
0 0.238
1 0.438
2 0.269
3 0.055
11.
P(at least one but at most two adults in the sample believes in the ghost )= P(x=1)+P(x=2)=0.437+0.269=0.707
P(at least one but at most two adults in the sample believes in the ghost )=70.7%
12. E(x)=n*p
here n=3 adults and p=0.38
E(x)=3*0.38=1.14
so we expect one adult out of three will believe in the ghosts.

Step-by-step explanation:
college website
Step-by-step explanation:
If sine theta is 3/5, taking the sine inverse will give you 36.87°.
4tan theta is 4 × tan36.87 = 3
3sin theta = 3 × sin36.87 = 1.8
6cos theta is 6× cos36.87 = 4.8
Therefore, it becomes 3 + 1.8 - 4.8 = 4.8 - 4.8
The answer is 0
