Answer: B. [tex]48.5\%[/tex]
Step-by-step explanation:
Given : A number cube is rolled with these results:
64 ones, 67 twos, 73 threes, 59 fours, 72 fives, and 71 sixes.
Even numbers : 2,4,6
The number of times of rolling even number = [tex]67+59+71=197[/tex]
Total outcomes = [tex]64+67+73+59+72+71=406[/tex]
Now, the experimental probability of rolling an even number :-
[tex]\dfrac{197}{406}[/tex]
In percent, [tex]\dfrac{197}{406}\times100=48.52216748\approx48.5\%[/tex]
Hence, the experimental probability of rolling an even number = [tex]48.5\%[/tex]
