Number on the Cube Number of Times Rolled
Natasha2012 [34]
Total number of times cube was rolled = 100.
Total number of times a 6 was rolled = 27.
Probability of rolling a 6 = \frac{27}{100}
Total number of times coin was tossed = 100.
Total number of times a head was tossed = 41.
Probability of tossing a head = \frac{41}{100}
Therefore, probability of rolling a 6 and tossing a head = \frac{27}{100}\times\frac{41}{100}=\frac{1107}{10000}
