The probability that detector B goes off is 0.75
The probability of an event is known to be the likelihood or chance for an event to occur.
From the given information let consider:
A = the time when detector A goes off, andB = the time when detector B goes offSince one or both of them always goes off, then:
P(A or B) = 1∴
Their complements will be zero, i.e.
P(A' and B') = 0Similarly, we are given that:
P(A and B') = 0.25Then;
P(A') = 0.35∴
The set probability for A will be:
P(A) = 1 - P(A')
P(A) = 1 - 0.35
P(A) = 0.65
Finally, the probability that detector B goes off can be computed as:
P(B) = P(A) P(B|A) +P(A') P(B|A')
P(B) = P(A) (1 - P(B|A')) + P(A') (1 - P(B'|A')
[tex]\mathbf{P(B) = P(A) (1-\dfrac{P(A \ and \ B')}{P(A)}) +P(A') (1 - \dfrac{P(A' \ and B')}{P(A')})}[/tex]
[tex]\mathbf{P(B) = 0.65 (1-\dfrac{0.25}{0.65}) +0.35 (1 - \dfrac{0}{0.35})}[/tex]
P(B) = 0.75

On a small planet, an astronaut uses a vertical force of 175 newtons to lift an 87. 5-kilogram boulder at constant velocity to a height of 0. 350 meter above the planet’s surface. What is the magnitude of the gravitational field strength on the surface of the planet?.
Since the boulder is raised with constant velocity, the net force on the boulder is zero, so that the boulder has weight 175 N on this planet. If its mass is 87.5 kg, then the acceleration due to gravity is g such that
175 N = (87.5 kg) g ⇒ g = (175 N) / (87.5 kg) = 2.00 N/kg = 2.00 m/s²

List the angles of ∆ abc from smallest to largest. Ab = 20, bc = 12, ca = 10.
The angle of the triangle ABC from smallest to largest are approximately 22°, 27° and 131°.
The sides of the triangle are as follows;
AB = 20
BC = 12
AC = 10
Let's find ∠A using cosine rule,
a² = b² + c² - 2bc cos A
cos A = b² + c² - a² / 2bc
Therefore,
cos A = 10² + 20² - 12² / 2 × 10 × 20
cos A = 100 + 400 - 144 / 400
cos A = 356 / 400
cos A = 0.89
A = cos⁻¹ 0.89
A = 27.1267531173
∠A ≈ 27°
Using sine rule let's find ∠B
12 / sin 27 = 10 / sin B
cross multiply
12 sin B = 10 sin 27
sin B = 10 sin 27 / 12
sin B = 10 × 0.45399049974 / 12
sin B = 4.5399049974 / 12
B = sin⁻¹ 0.37832541645
B = 22.2299936087
∠B = 22°
Using sum of triangle theorem let's find ∠C
∠C = 180 - 27 - 22
∠C = 131°
The angles from smallest to largest are approximately 22°, 27° and 131°.

Layla has a coin that has a 60\%60%60, percent chance of showing heads each time it is flipped. She is going to flip the coin 555 times. Let xxx represent the number of heads she gets. What is the probability that she gets more than 333 heads?.
The probability that she gets more than 3 heads is 0.3456.
There are only two possible outcomes for a fliped coin, either it is head, or it is tail. Since the result is independent of each other coins, the binomial distribution will be used.
Given the following parameters:
x is the number of successes = 5 (coin flipped 5 times) n is the number of trials p is the probability of success on a single trial = 0.6Using the binomial distribution formula:
[tex]P(X =x)=nC_x p^x (1-p)^{n-x}\\P(X =3) = 5C_3 \ (0.6)^3 (1-0.6)^{5-3}\\P(X =3) = 5C_3 \ (0.6)^3 (0.4)^{2}\\P(X=3)=0.3456[/tex]
Hence the probability that she gets more than 3 heads is 0.3456.
