Answer: 45
Step-by-step explanation:
[tex]\\[/tex]To calculate the probability of the number of times a 1 we appear , we have
[tex]\\[/tex]number of times a 1 appeared / Total number of times the die is rolled.
[tex]\\[/tex]Let x represent the number of times a 1 is gotten
[tex]\\[/tex]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
[tex]\\[/tex]0.3 = x / 150
[tex]\\[/tex]x = 150 x 0.3
[tex]\\[/tex]x = 45
