The probability of rolling a two's or a three's is 0.3388889 that is 34%.
Probability is possibility that "deals with the occurrences of random event".
According to the question,
A number cube is rolled 360 times
Probability of getting one's = 47
Probability of getting two's = 55
Probability of getting three's = 67
Probability of getting four's = 67
Probability of getting fives's = 35
Probability of getting six's = 89
Probability formula P(E) = [tex]\frac{Number of favorable events}{Total number of outcomes }[/tex]
In order to find probability of rolling a two's or a three's only add probability of getting two's and Probability of getting three's and then divided by total number of favorable events.
= [tex]\frac{55+67}{360}[/tex]
= [tex]\frac{122}{360} \\\\[/tex]
= [tex]\frac{61}{180}[/tex]
= 0.33888889
To find percentage of probability multiply 0.3388889 by 100.
= 0.338888889 × 100
= 33.8889% ≈ 34%.
Hence, the probability of rolling a two's or a three's is 0.3388889 that is 34%.
