The required probability is 3/4.We have to compute the probability
P(Female |Junior) because we have to find the probability of the female student and the given condition is that the student is junior.
Determine the total number of juniors.Juniors=2+6=8
<h3>What is the probability?</h3>
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.
Since the number of females who are junior is 6, determine the required probability.
P(Female|Junior)=6/8=3/4
Therefore, the required probability is 3/4.

#SPJ1
The speed during the first hour is the slope of the piece of line that shows the first hour on the graph.
Average speed is always=(distance covered)/(time to cover the distance)
Distance covered during the first hour = from 0 miles to 40 miles on the graph; that's 40 miles.
Time to cover the distance = from 0 hours to 1 hour on the graph; that's 1 hour
Average speed = (40 miles) / (1 hour)
Average speed during the first hour = 40 miles/hour

This problem refers to a parallel plate capacitor. There is
an electric field between the two plates. The working equation to be used is
the Gauss’s Law which is
Electric field = Surface charge density / ε0
The answer is -2.52 μC/m2.
Answer:
The minimum possible coefficient of static friction between the tires and the ground is 0.64.
Explanation:
if the μ is the coefficient of static friction and R is radius of the curve and v is the speed of the car then, one thing we know is that along the curve, the frictional force, f will be equal to the centripedal force, Fc and this relation is :
Fc = f
m×(v^2)/(R) = μ×m×g
(v^2)/(R) = g×μ
μ = (v^2)/(R×g)
= ((25)^2)/((100)×(9.8))
= 0.64
Therefore, the minimum possible coefficient of static friction between the tires and the ground is 0.64.
