Answer: 0.41 or 41%
Step-by-step explanation:
Given : The number of magazines = 20
The total number of reading material available =\(12+20+17=49\)
Now, the probability that stephen's next reading material is a magazine is given by :-
\(\text{P(magazine)}=\frac{\text{Number of magazines}}{\text{total reading material}}\\\\\Rightarrow\text{P(magazine)}=\frac{20}{49}\\\\\Rightarrow\text{P(magazine)}=0.408163265306\approx 0.41\)
In percent, \(0.41\times100=41\%\)
