Using the table, 5 tourists visited the museum but not the zoo.
The total number o tourists surveyed was 30.
Probability that the tourist visited the museum but didt not visit the zoo is
5/30 = 0.1666 or 16.67%
X+x+1+x+2+x+3=50
4x+6=50/-6
4x=50-6=44
x=44:4=11
⇒The 1st number is 11, the 2nd is 12, the 3rd is 13 and the 4th is 14.

If you don't understand something,please ask me.
We need to solve for R, This is really simple.
The original expression is:
R (r1 + r2) = r1r2
To solve for a certain variable, we need to get this variable alone on one side of the equation and equate it with the other side.
In the given expression, to get R alone on one side we have to eliminate (r1 + r2).
In order to do this, we will divide both sides by (r1 + r2).
Doing this, we get the solution as follows:
R = (r1r2) / (r1 + r2)
