Open in App
Solution

Solution :0.5 for each step

Number of times the die showed 1, 2, 3 or 6 = 170 + 155 + 160 + 185 = 670
Probability of getting a factor of 6 = 670/1000 = 0.67
Number of times the die showed 1, 3 or 5 = 170 + 160 + 180 = 510
Probability of getting an odd number = 510/1000 = 0.51
