Answer:
1/9
Step-by-step explanation:
probability of rolling a 6 = 1/6
probability of rolling a number less than 5 = 4/6
1/6 x 4/6 = 4/36 = 1/9

45/300 is the probability of blue because out of 300, 45 were blue than times by 1000
Answer:
Probability of more than 1 death in a corps in a year
12.52%
Probability of no deaths in a corps over 7 years
1.40%
Step-by-step explanation:
If the data collected follow a Poisson distribution with mean 0.61, then
Probability of k deaths in a year is
The probability of more than 1 death in a corps in a year would be
(1)
But the Taylor series around 0 for the exponential function is
So,
and
Replacing in (1), we obtain
or 12.52%
b)
The probability of 0 deaths in one year is
As the events are independent, the probability of 0 deaths over 7 years is the product of P(0) by itself 7 times:
or 1.40%
Answer:35
Simplifying
5(x + 20) = 7x + 30
Reorder the terms:
5(20 + x) = 7x + 30
(20 * 5 + x * 5) = 7x + 30
(100 + 5x) = 7x + 30
Reorder the terms:
100 + 5x = 30 + 7x
Solving
100 + 5x = 30 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
100 + 5x + -7x = 30 + 7x + -7x
Combine like terms: 5x + -7x = -2x
100 + -2x = 30 + 7x + -7x
Combine like terms: 7x + -7x = 0
100 + -2x = 30 + 0
100 + -2x = 30
Add '-100' to each side of the equation.
100 + -100 + -2x = 30 + -100
Combine like terms: 100 + -100 = 0
0 + -2x = 30 + -100
-2x = 30 + -100
Combine like terms: 30 + -100 = -70
-2x = -70
Divide each side by '-2'.
x = 35
Simplifying
x = 35
Hope it helps. Please tell me if im correct
Since there are forty rolls and the experimental probability is what you actually got and there were 10 total 3s and 6s rolled, the probability is 10/40, or 1/4.
