Okay, here we have this:
Considering the provided expression, we are going to solve it, so we obtain the following:

Finally we obtain that the expression is equal to 0.95°.
Answer:
The probability that the paint latex = 0.857
Step-by-step explanation:
From the given information:
Let consider X to be the event that the customer has purchased the latex paint
Let consider Y to be the event that the customer has purchased semigloss paint.
Now, the probability of X i.e. P(X) = 0.75
SInce X and Y are mutually exhaustive)
P(Y) = 1 - P(X)
P(Y) = 1 - 0.75
P(Y) = 0.25
Similarly, Let Consider Z be the event that the customer has purchased a roller.
We are being told that P(Z|X) = 0.6
P(Z|Y) = 0.30





Thus, the probability that the paint latex = 0.857
Answer:
250 students
Step-by-step explanation:
Given data
Let the total number of students be x
Number of students that plays instrument = 10
Hence
40% of x = 10
40/100*x= 100
0.4x=100
x=100/0.4
x= 250
Hence there are 250 students in total
