Answer:
P(X=2)=0.04129
Step-by-step explanation:
-This is a binomial probability problem whose function is expressed as;
-Given that p=0.6, n=8 , the probability that among the students in the sample exactly two are female is calculated as:
Hence, the probability of exactly two females is 0.04129
The sign of f on the interval -5/3 is negative
<h3>How to determine the sign?</h3>The function is given as:
f(x)=(2x−1)(3x+5)(x+1)
The zeros of the function are
x= -5/3, x= -1 and x= 1/2
Next, we plot the graph of the function
At x = -5/3, the function approaches negative infinity
This means that the sign of f on the interval -5/3 is negative
