Answer: 45
Step-by-step explanation:
To calculate the probability of the number of times a 1 we appear , we have
number of times a 1 appeared / Total number of times the die is rolled.
Let x represent the number of times a 1 is gotten
And we have been given the probability of getting a 1 and also the total number of times the die is being rolled , substituting this inside the formula above , we have
0.3 = x / 150
x = 150 x 0.3
x = 45
Okay. So, 15% is 15/100 and 33% is 33/100. 15 + 33 is 48. You leave the denominator the same, so the fraction is 48/100. However, the fraction needs to be simplified. Whatever you do to the numerator, we must do to the denominator. We can divide both numbers by 4 to get the simplified fraction form. 48/4 is 12. 100/4 is 25. There. The simplified fraction is 12/25. The answer is H: 12/25.
